Used them once. No sorry, 3 times. The first time the guy cut the wiper fluid hose and didn't reattach it, so it would just dump out under the car. Then the guy who came back to fix that didn't put my wiper arm back on the motor correctly so it just just twitched up and down instead of wiping. Ended up just going to their building and waiting around for someone to fix it and will never use them again. Least I didn't have to pay for it.
