I used it for about 30 mins and then the suction cup did not hold anymore? It fell of my dashboard, making my phone go flying on to the ground!The unit was really tight when i put them together because as a result they were very difficult to pull apart. To be honest though, this is an ok product. After 3 months mine fell off too.
Bad review
