Review on IKross 2-In-1 Cup Mount Holder: Perfectly Secure Tablet And Smartphone Holder For Your Car by Marco Carpenter

I've been using it for a couple weeks now and I'm really happy with it. This review focuses on the physical characteristics of the mount which you wouldn't know unless you held it and used it yourself.Everything is made of plastic (as opposed to metal), but it's about as nice as a plastic mount could possibly be. The part that goes in the cup holder is some sort of rubberized plastic which grips well. The mechanism it uses to tighten the cup part is very smooth and tight. I drive a jeep with rough suspension and 3 weeks of jostling haven't loosened or moved it (or any other parts) at all. The other plastic parts are not rubberized and they feel pretty solid, while not feeling brittle. NOTE: Be careful while tightening the base. If your car's cup holder is crappy or old or not well-supported, you could potentially crack the cup holder.You can rotate the "trunk" of the device, adjust the angle of the "arm" that holds the actual phone mount, and you can rotate the phone mount.The trunk is adjusted by pulling up slightly and rotating it. The mechanism used here seems to be a spring-loaded gear of some sort (similar to the gear teeth on an adjustable flagpole mount, though flagpole mounts are adjusted with a screw instead of being spring-loaded). It feels good. It's just tight enough that it would never turn on its own, but it doesn't require so much force that you would be worried about breaking the plastic.The arm is held at the preferred angle by a similar gear/teeth mechanism (also like an adjustable flagpole mount) which is held in place by a screw (with a knob on the end instead of a wingnut). Because it uses this toothed mechanism, it'll never slip. However, it also means you don't have an infinite number of angles to choose from. If I had to eyeball it, I'd say you can set it at 10 degree intervals maybe. I personally like this design and it's no detriment to me, since there are still many angle to choose from and it's pretty much guaranteed to never slip.I have an S7 with an otterbox defender case (which isn't a heavy phone) and the clamp fits it nicely. Anything bigger probably wouldn't fit, though. While driving over bumps, the top of the phone moves back and forth about a half centimeter in each direction. I suppose you have to expect some sort of play on a top-heavy device like this where the arm is 8 to 10 inches high. I haven't owned it long enough to determine if this will loosen or weaken the parts over time, but it doesn't seem to have caused any change so far.Overall, I love it and I'd highly recommend it.
