Re: ROCK JAW (Neck & Jaw Strengthener for boxers)
I don't think anyone's arguing that having a stronger neck/jaw won't help in boxing. Personally, though, I find it hard to believe that your product will strengthen the jaw to help take punches unless you have scientific evidence backing it up (customer testimonials and a challenge to say a complete sentence after using your product doesn't really convince me). I give you respect for creating a product that you believe in, but if I can offer some constructive criticism that might help with future sales:
-Get some research/experiments done (professionally) that proves your product does what it claims to do
-Package your product in a way that looks more appealing/professional and not like something just anyone can make at home
If you truly believe in your product and think it's vital for every boxer to have, I think you should be willing to invest some more money into R&D, packaging, and marketing. Again, no hate. Just my 2 cents.
