not worth it at all ..
its not strong , or maybe for not big dudes its maybe ok , but for me its was a waste of money ... and actually, i knew immediately after receiving it , without using it ... i tried to send back, totally new , and they didn't let me ... really bad customer service ... watch out before purchasing , really a pain in the ass to connect to bluetooth, it doesn't have a-battery, or you plugged or you cant use .
