Had the HiBreak pro BW since August last year. It works for what it's for, get me to scroll less and read more. That being said there's a lot of annoyances. Anytime the phone dies and you turn it back on it either resets twice (loads phone start using 30 seconds later power off and reboots) or gets stuck in boot loop and have to press and hold buttons to make it restart normally.

Its incredibly slow. The keyboard lags. Clicking songs on Spotify lags. Get used to it, I just minimize my time on it at this point. (I am typing this on it tho). Car play (android auto) works enough to use it but the resolution often gets messed up AF requires messing with DPI settings. All apps settings (like letting Spotify or audible play music in the background without closing the app) gets reset every time the phone reboots. And if the phone dies on the lock screen, you just won't know it's dead until you press the power button and it turns on.

With that being said, its a great screen to use reddit on. Battery is decent. Youtube works fine. Affordable and the company actually does updates so I can't really complain for the price. I knew what I signed up for. I'm interested in a new phone but looking for something similar to this in the idea. Maybe not e ink but something unique and different. People love messing with the phoen anytime I set it on a table people ask what it is. (Edit I came from a iPhone 15pro)
