8Bitdo Ultimate Mobile Gaming Controller for Android (Open Box)

I have no problems with this controller at all. It's light, stable, holds my phone properly, and the battery has lasted for a dozen hours at this point and only depleted by 10% so far. I haven't noticed perceived any lag that isn't caused by my phone or the game I'm playing, so if there is any, it's tolerably low. It holds my phone well and lets me adjust it vertically to where I want it to make it more comfortable to play playing down. It's actually more comfortable to play some games like this than on a steam deck. I'm not a fan of the xbox style of controller layout with dpad under analog stick, because it makes it not an option to occasionally tap the dpad with the index finger. However you can tell that it has this layout by looking at it, so it's not really a product problem, just my preference being different. PS: if you're like me and playing genshin and having problems with the deadzone being big, that's genshin's fault!
