Replying to The Steezycam Steadicam for gopro and dlsr feedback

Hey everyone! i just invented my rendition of a merlin steadicam, as of right now its made to support any gopro with any housing, and my next design model will be a model for dslrs over 5lbs. also ill be making glidecams in the near future. ill be selling these ones once finalized and cleaned up for under 100 dollars! if you look online comparing these to other handheld stabilizers youll see mine is better! here is a demo video of it with a quick sample demo of it with some walking and skating!
please give me some feedback on what you think!
