Came with glass, was not expecting it, took a while to remove. also, mainly close to edges and applies when you try to click the top bar of a window to close or minimize something, the driver recognizes something like 100 clicks in less than a second so you need to set up some settings, probably work through the registry to manually set up a really slow double click speed because if you double click anywhere in a window bar it resizes it, and this is pretty annoying, otherwise this thing is amazing, its natively accepted by windows like a touch screen and is just great, but the double click JUST for this device is a tricky thing to set up
