I purchased this because I occasionally need to mount a pico projector to the ceiling and going through the hassle of a traditional fixed projector mount simply wasn't worth it. Sadly, after receiving the device I found it simply would not suction to my ceiling, which isn't the manufacturers fault since the item listing and instructions pretty clearly warn it won't work on porous surfaces. I don't return items that work as described, but didn't fill my niche needs so I ran it through some tests to see what surfaces it would stick too. For each test I stuck it on a vertical surface and left it for at least an hour. A 'No' means it didn't last an hour.Bare Drywall - NoOld painted drywall - NoOld wallpapered drywall - NoNew wallpapered drywall - NoNew painted drywall - YesBare plaster wall - NoPlaster wall with some paint - NoPlaster wall with a ton of paint - YesPlaster wall with wallpaper - NoGlazed Ceramic Tile - YesUnglazed Ceramic - NoWood - No -=I tried a lot of different wood. The only piece of wood that I could get suction to was oak, and had been stained and sealed by myself with over 10 coats of wood sealer. Pretty sure almost all wood is out=-Various types of plastic (HIPS, ABS, the side of my PS4, my HP Printer) - YesAny vinyl sticker like covered surface, not vinyl fabric (including cheap covered particle board that is supposed to look like wood) - YesVinyl Fabric - NoMetal (Aluminum, Steel beam, the side of my Chevy HHR) - YesGlass (Windows, automotive glass, mirrors, super cheap mirrors) - YesHardback Books (I was bored) - NoHope this review helps someone. One last warning, the user manual warns about it, but this item will definitely leave a black ring around any whitish object it's affixed to. It'll come off with some elbow grease, just don't go slapping it onto your parents walls willy nilly.
