This is a well-made tool. The fit and finish is very nice and it has a quality \"feel\" to it. It comes with simple instructions, a pair of gloves, a glass cleaning cloth, and a very nice carrying/storage case. I really did not expect such a nice storage case. This is to be used for carrying non-porous materials, such as glass. While I have no way to measure the amount of suction, it does have very good suction once it grips the item. The only problem I have with it is that there is not enough flexibility to use it for glass that has a slight curve to it. I got this so I could hold up an automobile door window. The auto window has a slight curve to it and the tool would not grip it at all. For those types of windows, you apparently need the glass handlers that have two small suction cups instead of one large suction cup like this one. In summary, this works well for some purposes, but not others.
