I got this in black for my P3P. Cannot use it. It's a little loose and needs to be secured somehow. Flying with a small bit of tape overwhelms the gimbal, weight-wise, and causes it to stop working repeatedly during the flight. He has released a v2 of it, but would be careful until test reports come out. I'm out $18.49. (Even though v2 dropped the price too!)
UPDATE: Messaged seller (James) on Shapeways. Got a quick reply. Not the only one to have trouble with v1. Going to test out v2, which looks better and lighter. Will let you know.
