Very good, solid mount for phones. Its done a fair few miles of road and some gravel/light trail use with no signs of wear or fear of the phone coming off. I use this with a Sony Z5 compact and the mount is very well sized for this.
Whilst it did come with some free map downloads, I can't say I'm a fan of the software as I use Strava anyway.
EDIT 2 years on: Now after a couple of years use, one of the middle holders snapped. Its more difficult to use on my new bike, but even with it 'broken' it still held my phone on a fairly brutal gravel ride. Still top marks, new one ordered.
