Review on IMT 10" Heavy Duty Glass Suction Cup With Handle And Free Case - Ideal For Granite Lifting, Window Replacement, And Panel Carrying by Cornelius Reeves

**EDIT UPDATE**We have been using this in our shop for a little less than 3 months before they broke. Both of them will no longer hold anything and the button you press in is just stuck. I tried contacting seller, but no answer. Buy with caution knowing that they wont last.**ORIGINAL REVIEW**Use these for picking stone slabs up and moving them around. We had some smaller ones that were slipping on heavy material. These can definitely handle the weight they are rated at. We have had no problems with them slipping off material. Hopefully they last as long as well as they work.
