Query: read before you buy

If you are buying the AAXA P4 P4X Pico Projector, 95 Lumens, Pocket Size, Li-Ion Battery, HDMI, Media Player, 15,000 Hour LED, DLP Projector, don't buy this tripod. There is already one included with the projector. I also found this type of tripod to be EXTREMELY unstable. I would rather put this expensive projector on a pillow or beanbag to be safer.
