DONNO.co review: Personal hand strengthener, refuse to respond

Tried to return an item but they refuse to respond to my request for an address to return it to. They item does not wor, too small, and they say it is easy to return it. It is not. They say two days and it has been almost 10 days to just get an address and still no address. They respond with we’ll get back you but they will not. No phone number. No return address. Ripoff Chinese company, not in US. Do not buy stuff off Twitter or YouTube, they are rip offs, HOZA.co is one of their companies also. BEWARE.
