Review on IFYOO Yao L1 PRO Mobile Game Controller: Unleash the Ultimate Gaming Experience on iPhone (iOS 13.4 or Later)! by Rick Ross

Disappointed in using for Genshin. These controls are great for movement, but will probably help you aim better. It's inconvenient to have control at only one end of the phone. If it had been a two piece set for each side I might have used it more often. It's also not practical that you have to use it without a case. Most people lock their phones, and it's not very good to take them off for a not-well-protected check. With the touchscreen I get more security and control than with this control. Can help with some minigames but generally won't use it. On a basic level, yes, it replaces motion controls. Connects easily. Cozy. No, it doesn't suck. Cannot be used with a suitcase. The button cover often falls off.
