I gave this holder a fair chance, but after it fell once, I adjusted it and tightened it more, thinking it might have been user error. Unfortunately, it fell again, and this time it startled me so badly that I almost got into an accident. That should never happen with a product meant to hold your phone securely while driving. When the phone drops hard into the center console with a loud thud, it is not only nerve-racking, but it also risks damaging both the phone and the car. Most importantly, it creates a real safety hazard. I would not recommend this product.

Secure Mount that doesn't use Adhesives or Magsafe

Bought another phone mount prior to this one that relied on a sticky adhesive to attach to the back of the screen, which ended up falling off after a couple weeks (might be due to hotter weather in my area as well). This mount is much more secure due to actually attaching to the corner of the screen. The mounting stabilizers for the phone also work well and feel smooth - they are also wide enough to fit any phone. The mount also doesn't rely on magsafe, so it's compatible with androids without that functionality. The bad reviews on this product seem to mention that it can potentially damage the screen, but I think that's only if you heavily overtighten the mount.

Love the T-la Phone Holder!

This phone holder is probably the best I have ever owned. It does NOT shake loose and it displays right where I need to see the phone. It is safe to use and a great size (I have a Note). I think this is really high quality and I am very happy with this purchase.
