The idea is great! but I think the price is a bit high, maybe reducing the size of parts you can reduce costs and final price
I'm thinking in back it, depends on the Shipping Price (I'm on South America).
Regards, and good luck
I like the visual work, design of photos looks cool. I love gifs cause they explain better. But my impression is the product is focus in a specific segment: runners, maybe you can include more benefits to use in other dailys rutines.
