I accidentally purchased this thinking it was for my eufy robot vacume. I dont have an irobot. I immediately requested refund many times. It was denied. I have no use for this. I consider this theft by google play@!!!!!!@! You will be hearing from my attorney. I WILL NEVER MAKE A PURCHASE WITH GOOGLE PLAY AGAIN This says installed. Guess what???? It's not installed on my phone cause I cant use the **** Thing..
