The GPX projector is pretty cool, only downfall is that the Bluetooth to iPhone compatibility sucks, not sure about with android.. but I wouldn’t chance it if you are counting on that one feature because another review stated the same. Also the screen doesn’t adjust to being any bigger or higher or lower, etc.. you can only zoom out, not in. I wish you could move the projection however you like, but you actually have to have it in whatever fixed position you want it to show in. Hope this helps.
