I've used a few of these for GPS' and ECU Tuners, and they work great! You can't find a slimmer mounting solution then this. It gives you the choice to use VHB tape to mount to your device and then either VHB or a vent mount to use on your vehicle. Gives you enough for two applications, in case you move the device to multiple vehicles. It's strong, I've never had the adhesive try to come off on it's own or shift (been about a year since my first use). I was able to remove one of them from my dashboard and it came up fine - at least no lasting residue or noticeable mark (use fish line to separate, then something like goo-gone to clean up). All in all for the price and quality you really can't beat it.
