After having the RWD mount for my 800 for a couple months now I am torn.
On one hand it is the lightest option out there looks good and puts the Garmin in a good location.
On the other I am really starting to wonder if it will last. I have already resorted to putting tape on the mount to tighten the interface to the Garmin.
With that I still feel it's too loose. Engagement is poor and it has a bit of play and vibrates with the tape.
Being an early adopter I missed out any any improvements made. Worst part is I have told others where to get it and they are complaining they are never in stock.
I am sorry that your having troubles with your early mount, I will PM you later and see if i cant help to resolve this problem for you. Also have to apologise for being out of stock, demand has far out weighed my expectations and as soon as I have stock it sells out. As this is only a side line for fun and not my main job i had little resource to invest in stock, however I now have 150 mounts on ordered due for delivery next week so hope this will last longer than a few day this time.
