Awhile back, someone on this site recommended this product. I was thinking of buying one because I need something to hold up my phone while I am in my car. My phone has a case on it BTW (Trentium 6L case). I am hesitant though because I see a lot of bad reviews on Amazon for it. Some people say it doesn't hold the phone tight enough causing the phone to drop out. Others say the grips are cheap and fall off. And some others say that it doesn't fit the iphone 6+ if the phone has a case on it. One person even said that the knockoff version works better than the name-brand model. I really don't want to buy this if I am going to have to pay return shipping if it turns out to be bad. Can anyone confirm or deny what these negative reviews are saying?
