Query: Works great!

All you need is a pinch. Works well with glass shelves. Clear and invisible so you wont see it even if you look from the bottom. For what its intended purpose, it is 5 stars. Other than that, it is limited in uses.You cannot use it to stick posters or practically anything on the wall as it drips. It is not as sticky as other products like "Quakehold", poster putties, etc. It will also not work on wooden surfaces. Anything that has pores and grains will not work.
