Review on 🔌 Ultimate Cleaning Power: Electric Toothbrush with Ultrasonic Charging—Highly Recommended! by Monica Woods

I recorded a video in the first 3 days of use and the next day I had to charge it. I quickly noticed that the toothbrush was only charged for 40 minutes - 1 hour of use, i.e. 4 minutes a day. In fact, the instructions say to charge after 10-15 days of use. Why do I have 3 days? I bought it for 3 children. All use different nozzles, distinguished by colored rubber bands (there are 4 of them in the kit). My kids were so happy to finally have their own electric toothbrush that they tried different modes every time they brushed. Has 5 different modes. So about 20 minutes of use per day (thanks to snowy days). I charged the toothbrush before using it for the first time. All it has is an indicator that changes color from red to green. So, on the 4th day the battery was dead. Charged after the green light turned on, turned on for a second or two. Left it charging for another hour. After about 2 hours of charging, it suddenly buzzed and scared my kids, but it still can't be used. I connect and charge for about 7 hours total but still can't use it. It worked fine for the first 3 days, but I'll be back. Maybe I have a lemon.
