Query: Poor workmanship

The first one lasted one year and then stopped sticking to the windscreen. Instead of replacing only the suction piece, I had to replace the entire set (because Garmin will not provide pieces only). Spent $50 again and new set broke right where the mount sticks to the suction in less than a month.My new GPS is not going to be Garmin.
