Hi Slotplayer
Foxwoods & The Mohegan Sun have had them for awhile now.
At first I hated them but they grow on ya lol.
And least one thing your hands are cleaner.and they do take the germs away to a point.
I live at Foxwoods & The Sun and The Mohegan Sun to me is cleaner too. The air is always freasher. I wish they would come back with a Bingo Hall I would run more bus trips.
