I hate this phone holder so much. At first, I thought I'd try it for my phone, which is the largest, heaviest phone brick you could ever imagine. (It's a rugged phone, so ... just imagine someone asking "what kind of case are you using?" when you're not using a case)Anyway, it fits the WIDTH of my phone (the description was nice enough to tell us its max width before purchasing). However, it's unusable for my phone because it REQUIRES that the phone align perfectly with the built-in charging port. It only allows you to slide the charging port forward maybe a centimeter, which sadly isn't enough.So in order to validate this product, I gave it to my daughter who has a very average-shaped phone. There's a bit of a trick to setting it up; you need to get it to the right point (just putting your phone in and tightening is NOT quite right) and THEN tighten it.Once you've got it set for your phone, then you have to learn how to use it. Just ... study the photos they have here and you can figure it out. SIGH. I have absolutely used phone holders that are many times easier to use than this one.
