Excellent for placing phone at the right distance and viewing angle.
However, mounting the whole unit can be a problem. There is a suction cup which simply doesn't work on most car surfaces, unless you're mounting it on the windscreen. (I didn't try this because it's a bit far from where I want the phone to be). Certainly won't stick to the dashboard even if it's completely smooth. The unit comes with a separate plate with a Magic mount sticky surface, but the suction cup won't stick to the back of that either. I had to improvise and stick the suction cup to the magic mount plate with adhesive! If you're happy to do a bit of DIY, or if you can make it stick to the windscreen, I'd highly recommend this unit, but otherwise not.
