160: Red Star Smart Electric Toothbrush Review

"Hello everyone, I'm Ji Feibai, a smart device uploader. First of all, I wish everyone a happy May Day Labor Day and hope you have a great time.

Today, I'm bringing you an unboxing review of Red Star's latest release, the classmate xiao xing assistant touchscreen version and the smart electric toothbrush."

"Let's unbox first. This time I got the Red Star Electric Toothbrush Premium Edition. The packaging is quite simple, and there are a lot of air cushions inside the box for padding."

"The delivery speed was indeed very fast this time. Thanks to the SF Express guy for delivering it to me early this morning."

Compared to his previous life, because the popularization of smartphones was progressing faster now, Chen Chen felt that the short video trend would arrive earlier than the normal timeline. Therefore, he had already laid out plans for some video bloggers.

Currently, long videos were still the mainstream. As the third-largest shareholder of ByteDance, Chen Chen knew that Zhang Yiming would launch several short video software apps this year, taking advantage of the first year of 4G. Of course, Red Star was also pushing this behind the scenes.

In the era of short videos, short video software would be a massive traffic entry point and a tool for controlling public opinion and outputting values.

Originally, Red Star was the second-largest shareholder of ByteDance. During the angel and Series A funding stages, Red Star Investment had focused its investment on Zhang Yiming.

However, in the Series A+ and Series B funding rounds early this year, Zhang Yiming introduced other capital, causing Red Star's shareholding to drop from second to third. Lei Jun's Shunwei Capital had also invested in Zhang Yiming during the Series A round, and its current shareholding was second only to Red Star's.

The Red Star marketing department mainly supported several individual uploaders like Old Fish Talks Phones, Ji Feibai, and Dabai Reviews. Chen Chen felt that Ji Feibai's last review of classmate xiao xing was well done and had great potential, so he told his subordinates to give him special attention.

Otherwise, whose delivery could be this fast? Receiving the goods just three days after the press conference.

"How can a toothbrush be related to 'smart'? Today's video will tell you a lot of things that President Chen didn't mention at the press conference. Opening the toothbrush packaging, the contents inside are very simple."

"A manual and a quick start guide telling you how to use it."

"I suggest everyone read the manual carefully, after all, many friends are using an electric toothbrush for the first time."

"Below the quick start guide is the main body of the toothbrush. Inside the accessories box, there is a charger and three brush heads."

"The brush heads are all vacuum-packed, and each brush head has an individual cover, which is a nice touch."

"As for this charger, it's a wireless charger, which is really rare to see on the market. I don't know what the power is, we'll do a charging test later."

"Using a wireless charger allows the entire toothbrush body to be integrated, making it easier to achieve waterproofing. This Red Star smart electric toothbrush supports IPX8 dust and water resistance, so it's fine for everyone to rinse it directly with water."

"Just pick up the toothbrush body and put it on to charge, nothing much to say about that."

"Except for the slot on this base; you can see it's not a perfect circle. You might have to align it when putting it down because there's a front and back. I don't know why it was designed this way, why not make it a perfect circle?"

"The bottom of the charger has some information: five volts and one ampere of charging power. This wireless power is absolutely enough for a device like an electric toothbrush. I estimate the cable length to be about seventy or eighty centimeters."

"I'm just curious, even electric toothbrushes are using wireless charging now, so why doesn't any Red Star Mobile Phone support wireless charging yet?"

"I hope President Chen sees this and considers it, arranging wireless charging for Red Star phones as soon as possible. Personally, I think wireless charging is quite convenient, so you don't have to pull the cable back and forth every time."

"Let's open the Xingkong APP on classmate xiao xing and prepare to connect."

With the launch of Xingyao OS 4.0, the home device control center software was renamed Xingkong. Chen Chen had originally named it Xingjia, which was essentially following Lei Jun's path.

If I call it Xingjia, will your Mijia still be able to launch?

As it turned out, it was already 2014, and Xiaomi didn't have many smart devices, let alone the launch of Mijia.

Lei Jun: I ******.

The meaning of the name Xingkong was also very simple. In the Starry Sky, every Red Star smart device is a star, and eventually, countless stars together build the entire Starry Sky, which also constitutes a home.

"The device is connected to Xingkong. Let's click and take a look. There are no quick operations. Everyone, pay attention to the top; it has already connected to my device via Bluetooth."

"By the way, if you haven't purchased the classmate xiao xing assistant touchscreen version, you can also connect via mobile phone Bluetooth or through the Red Star Gateway."

"The connection speed is very fast, there's no time spent searching for devices, it connects directly. This is a plus. You should know that when I used the Red Star electric fan back then, that WiFi direct connection almost made me collapse—constantly scanning, then constantly failing to connect."

"However, after several version updates, these problems are gone now. Most devices don't even need to be searched for; opening the Xingkong app basically allows for a direct connection."

"The connection speed through the classmate xiao xing assistant touchscreen version is fantastic. I hope Red Star keeps it up. And the 8-inch screen is indeed much more convenient to operate."

"Entering the toothbrush interface, there are health reports and a battery display."

"Since I haven't used it yet, the dental plaque risk and gum risk columns are both in a safe state. This should change based on our brushing time, frequency, and angle."

"Smart adjustment, this is interesting. It will make some dynamic adjustments based on your actual usage. I'll go brush my teeth and try it out first, and you guys can see what changes in this interface."

As Ji Feibai left with the toothbrush in the video, the connection on the classmate xiao xing assistant touchscreen version did not disconnect. Netizens who saw this began to send bullet comments incessantly.

"No way, is Red Star that insane? Even a toothbrush needs to be connected to the internet?"

"Haha, this is what true networking is. The interesting part is yet to come. Didn't you hear President Chen say this toothbrush can even sing?"

"Singing? I want a toothbrush to sing to me?"

"Listening to music while brushing your teeth?"

"The connection speed of the classmate xiao xing assistant touchscreen version is indeed much faster than a regular gateway. I don't know how big Ji Feibai's house is, but anyway, one gateway isn't enough for my house. The temperature and humidity meter in the bedroom always goes offline."

"Going offline? Mine is also in the bedroom, and the gateway is in the study, it has never gone offline. How big is your house?"

"Just over 290 square meters. That Red Star robot vacuum has to sweep for over three hours every time, and it even has to go back to recharge once in the middle. So annoying."

"Over 290 square meters? Not small, not small, it's almost as big as my bedroom."

"May I ask if the person upstairs is a novel heroine who wakes up every day on an 80-square-meter bed, and whose bedroom is 2 li away from the living room?"

Soon, Ji Feibai finished brushing his teeth and returned to the camera, "I tried it out, the effect is good."

After saying that, he turned the classmate xiao xing around to check the data on it, "The data transmission speed is very fast. I just came back from brushing my teeth and the data from just now is already there."

"Because it's a test, I tried all sorts of tricky angles just now, and it actually extended my brushing time by 30 seconds."

"Maybe it felt that my oral cleaning wasn't thorough enough, so it helped me extend the time."

"What's interesting is that my brushing angle was wrong just now, and this toothbrush actually kept reminding me that the angle was wrong and told me to correct it."

"In the mode selection, there are smart and custom modes. I just used the smart mode. You can choose freely according to your needs."

"There's also a 'brush head remaining' section. It's not in days here, but directly in times."

"179 times remaining, which means three months. Twice a day is about 180 times before replacement."

"This brush head isn't expensive either. I checked the Red Star Mall and it's about 19 yuan. There are three brush heads included in the package, so basically, we don't need to buy brush heads for the first year."

"In the upper right corner, there's more device information. Let me open it. You can see some common things here, like the gateway connection. Of course, if you don't have a gateway, you can also connect directly with your phone."

"There's also a novice guide, quick start guide, health knowledge, etc."

"Accessibility features? This is interesting. You can choose the color of the light ring here."

"As you can see, after I set it, the ring on the toothbrush—note it's the top ring, the light ring color below the brush head connection—will change."

"For example, if your family buys the same model, right? You think, hey, this toothbrush is good, and you buy the same one, and then they all look exactly the same."

"Then how do you know which one is which, and which one is yours? This custom light ring color can distinguish them."

"Of course, this toothbrush also comes in two colors. Mine is white, and there's also a black style."

"Let's look at the smart linkage here. There are still devices that can be linked. For example, if I'm going to sleep after brushing my teeth at night, I can link it to the Red Star lights or wall switches to turn off the bathroom light one minute after I finish brushing."

"It can also push a message to my phone when the toothbrush battery is low or the brush head is about to run out."

"The last interesting point is that this toothbrush actually sings!"

"Can you believe it actually sings!"

"When I went to test it just now, I heard the sound of the toothbrush coming from between my teeth, saying my angle was wrong!"

"As for the principle, there's a gyroscope chip built into the toothbrush that can detect our brushing angle in real-time. When there's a deviation in the angle, the toothbrush head makes a sound through bone conduction technology to remind us."

"And!"

"Listen to me, and only you can hear this sound!"

"bone conduction technology uses vibration to directly make our skull produce sound; others cannot hear it."

"There's a music selection in the toothbrush interface. Several songs are built-in from the factory, and you can also write your favorite songs through customization. Let me find something to test it for you."

Soon, Ji Feibai returned to the camera with an empty water dispenser bucket, "Family, look what I found! A perfect speaker bucket!"

In the video, Ji Feibai turned on the toothbrush and selected music playback, but no sound came out of the toothbrush at all. When Ji Feibai pulled the microphone closer, only the sound of the toothbrush's high-speed vibration could be heard.

"Look closely, everyone, there's no sound at all right now." As Ji Feibai pressed the toothbrush tightly against the water bucket, the sound of the most popular hit song of 2013 suddenly came through: "Oppa Gangnam Style! Gangnam Style!"

"Najeneun ttasaroun inganjeogin yeoja!"

"Keopi han janui yeoyureul aneun pumgyeok inneun yeoja!"

"How is it? The sound quality of the water bucket is pretty good, right? Does it have that Harman Kardon vibe!?"

"Wow wow wow! As expected of a top-tier amplifier bucket, this feeling is unparalleled. This toothbrush solves the trouble of not being able to listen to music while brushing. Think about it, how cool is it to listen to music while brushing your teeth!"

"You ask why not use a speaker? Anyway, it's just a matter of a sentence to xiao xing. This student clearly doesn't have children yet."

"This toothbrush is indeed useful. Last night after brushing my teeth, I went out for a walk. As soon as I opened my mouth, the people in the village thought it was dawn and all got up to start working."

"Do you think it's possible the gyroscope on the toothbrush can be taken off and installed on a drone?"

"Just put four rotors on the toothbrush. Anyway, the flight control is already there. There's potential here, brother!"

"Drone? You mean the enemy being blown up by a bunch of toothbrushes going 100 kilometers per hour?"

"Red Star Smart Toothbrush, not only makes your mouth feel good but can also take you flying!"

"Now that you put it that way, doesn't this 999 price tag seem a bit attractive?"

PS: Too lazy to split the chapters, two big chapters.
