I have used mine a couple times and they are amazing for lifting heavy glass. Moved a 260 and a 300 with only 4 cups.Anyone out there have any experience using suction cups to lift and move a tank? I have seen a couple threads of people recommending them to others, but haven't seen much as far as "real world results" go. Any risk of glass scratching? Anyone have them FAIL during a lift or move?
