Five Star: I have a sheet of glass over my kitchen table and the coffee table in the family room. I bought a pair of these to help lift the rather large pieces of glass off the tables to clean them. These worked great for this purpose and made the job much easier. I was a little hesitant using them at first, but as the warning says, always secure the object lifted with your other hand. I haven't had a problem thus far. I also found them very useful lifting and manipulating larger formal tiles during installation. They make moving and positioning the tiles much easier, particularly tiling a wall. The have good power and work well. They do lose suction over time, so take that into consideration.
