It's light-weight and it holds my Garmin securely. I ride a lot on trails with root and rocky sections that shake the bike up pretty well...in addition to the occasional wheelies and jumps and my Garmin has never come loose. I used to want to safety wire my Garmin, with the SRAM mount I lock it in and forget about it...no worries about it falling out.Plus it make the Garmin display a lot easier to glance at when riding/racing.
This has been a solid and reliable mount, which I've used on both road and mountain bikes. It fits securely to the now common 31.8mm bars. Smaller diameter bars will require you to find and use a spacer. Note that the bolt requires a Torx wrench, not an allen wrench.
Overall, a great mount for the Garmin 800 Edge. With the mount positioned forward of the bars, the screen is much easier to see. The mount can also be positioned behind the bar, on a mountain bike, for more computer protection. Either way, the computer will not be ejecting, once it's mounted. This mount is well-worth the price.
With a short 70mm stem on my 29er, I couldn't mount a garmin 800 on the stem with the garmin elastic band mount as there is no space. With this Quickview mount, I can have the Garmin 800 mounted just above the stem, and it's perfectly out of the way of your knees hitting it, or from potential damage from a crash. Mounted just above the stem is where you want it to be if you have a 500/800 mounted on a MTB or CX bike. Highly Recommended!
