Review on DAMO Vacuum Suction Granite Lifting by Wendy Moore

DAMO suction cups are very strong and reliable - they never slip. Used to move my 300lb tank and worked perfectly! Worked better than my expectations and as advertised. Non-slip and easy to use. Just pump the piston until it can't pump anymore and you're good to go. To release, simply squeeze the lever on the opposite end of the pump. Highly recommended! Really hard work!
