I travel frequently for work and rent cars 2-3 times a month, usually after a long flight. I initially used one of the Garmin friction mounts which worked very well and was easy to pack and re-assemble; but when I switched GPS brands, this was no longer an option. I could have used one of the other generic friction bases, but they require the use of the native device's mount which are clumsy and aren't easy to pack and set up. When I saw this Bracketron case and mount, I thought it would be the perfect solution. I quickly learned that this wasn't the case.
Pros:
--On a basic level, the mount does what it says. It will hold your GPS, and it prevents dashboard movement as much as could reasonably be expected given the build of the device. It hold steady for basic driving.
--As long as you don't need your power cord, it is very easy to setup.
Cons:
--If you're driving for any length of time, the heat from the GPS starts to melt the adhesive that attaches the velcro strip to the GPS. Once this happens, the GPS falls out of the case, rendering it useless. I was driving from Boston to NYC, and by the time I got to New Haven, the GPS was resting in the seat next to me because I couldn't get it to stay in the case.
--It can be tricky to connect the AC adapter to your GPS device. If your adapter has an L-shaped connector, or has any kind of bulky piece at the end, it can be tricky to connect, and can prevent the velcro pieces from being completely flush together. This again can cause the GPS to pop out of the case while driving.
--This thing is impossible to get through airport security. The first time I tried, with the GPS inside, the case zippered and resting in my carry-on, I thought it was a fluke. I tried going through security with the case open, closed, in my carry-on, in the bin, every possible way, and security flagged it every time for extra inspection. There's something within the bean bag base that doesn't play nicely with TSA Xray machines. For anyone who is a frequent flyer, this is show stopper.
--The sound does get muffled by the case. If you're on the highway and playing music, the GPS can be difficult to hear, especially since most people won't max out the GPS volume because of distortion.
All told, if you're not doing much driving, this device should work just fine for you. But if you're like me, a frequent traveler looking for a means to easily port your GPS from vehicle to vehicle, find another solution.
