Just bought mine today for my Xs Max and i think i will keep it. Phone is easier to hold and type, got no problems with the buttons. Mine also came completely dead, i used the 29w fast charger to charge it, now it’s good to go!
I also would like to get the 2 battery icons permanently on the lock screen... the ones when you plug or unplug the charger, or they could show the battery status of the case instead of the phone’s battery until the case is dead.
