If ur friend can make a mold of the actual back battery door on the rezound instead of just the case, Ill definitely buy one. I dont like the back and red theme so I dont like that red beats audio logo on back. If he could make it and possible paint it black and purple ill buy it from him
Well, that is what we are working out.
First you have the idea, and you set a target price point.
If there is sufficient demand, you get to work and see what you can come up with, both from a product perspective and then from a cost/profitability angle.
If yes on both counts, you test and perfect the prototype, and if it all works out and you still have demand and can create it at a price point that sells and meets your margins, GREAT SUCCESS. ;)
