Do you have any suggestions to improve our product?
different sizes and more designs
how do you want to produce that by yourself?
micro usb
no offense guys, but you should try to think of something original that hasn't been done before. in the ad campaign, i would suggest showing how robust the stick is because if you carry it on your keychain, it has to withstand a lot of pressure over time. the usb port must not bend or anything under any circumstances; that's pretty important (at least to me).
