The only downside I've noticed is that there was no way to lock the screwdriver in forward or backward mode. Luckily this repository exists with firmware for this screwddriver. After examining the firmware there are lots of cool features - and everything can be automated - even different torque patterns in sequence for instance. For my needs I added a few modes: double tap the button to run forwards, tripple to run backwards, and four times for menu. You can find the modified code below this post. So far this tool with the extra modes has been really useful. Having a mode where it runs constantly means you avoid any of the grip issues it has. And boy does this thing have a lot of torque for such a small screwdriver. You can find my custom firmware below - I hope it's useful for anyone. You can follow the guide here to flash your own with custom firmware.
