I'm not certain they will consider those to be broken. If it didn't come with a bezel, then it's basically just an LCD monitor with the touch glass "stickied" on the front. The first one I received from them, there was no bezel, and I strung the whole thing up with wires from the ceiling so I could play with it. I came back down a little while later and the touch glass was dangling above the floor by the signal cable. Good thing it held, or I'd have had a floor covered with glass!
If it has a bezel, then the bezel holds the glass in place. But if there is no bezel, then be aware it's only held on by some sticky stuff, and it could easily unsticky under just the normal pull of gravity....so some care has to be given.
But if you have the touch glass in one piece, and it's still attached to the LCD part by the control cable, then just place the glass back on the front of the thing, and it SHOULD still work. You'll just have to take care to secure the glass when you install it in the wall.
Edit: Looking at the link MavRic posted a few pages back, those are the ones without the bezel...so the glass on front is only held on by kind of double-sided weather stripping...almost a tarry gum. Just center it back up on the display, press it down, fire up the ELO software and re-calibrate it, and I think you'll be ok.
Other than that, when I did have to return one (USB connection did not work), I had absolutely no problems. I worked with Stephen, and was very happy with the service they provided....so try to be patient and give them a chance or at least talk to them and see if what you're experiencing is normal or not. They are definitely not a scammer outfit.
BSR, I'd say you're right...but I'm guessing they got these touchscreens *cheap* from salvage, and so selling even 1 probably covers the shipping costs for several. They didn't even bother to have me return my "defective" one. I'd guess shipping probably costs more than the touchscreens did for them.
