Only a week with the Scosche mount... But I assure you (like MrM said) it is not moving. Solid and safe. A great way to hold the Mobius. Quick release and you don't leave behind something ugly.
Yes it is. But as mentioned, my mount fell off several times due to the California heat. The sticker remained on the windshield. So apparently the other side didn't bond well with the plate. So I've removed the 3M that Scosche uses. Cleaned it up, and used Sugru to stick the plate to my windshield. Lets see if this is really temperature resistant.
