I ordered 2 of these units, my expectations were modest. I didn't expect such a powerful device. However, as they say, I expected an accurate description. When I received the devices, one of them had a few blisters under the pre-installed screen protector, I notified Revain and had a replacement in my hands the next day. Now for the main problems. Claimed battery life is around 12 hours. Far from it. When setting up the device, I noticed that the batteries go from 100 to 65 per hour. I charged after setting and tested the film on both. At 100% charge, both devices barely lasted 2 hours and 20 minutes. no bueno. I could almost accept that if the USB-C port was fully functional. it is not. data port only. weak and without the possibility of charging with the power bank on the way, I decided to return both devices because the descriptions are not correct. Unfortunately, I liked the screen overall and the performance was okay for the price. But as a true wireless device, it can't be used with such a bad battery.
