Review on IMT Suction Window Granite Lifting by David Carter

We have used these to repair some pool bottom panels (12" x 12" and 18" x 18"). Positions are much easier. I'm not sure how long it will last, but it's held up well enough not to drop anything. Of course, the suction power depends on the porosity and surface of the object to be picked up. On glass it's like cement. While I don't think they will hold up to everyday professional use, they are perfect for the homeowner and get the job done at a great price. Good price!
