I've never had any luck peeling one. It breaks the antenna piece in it when you peel them off.
9 days till we leave for the fort... I will be so glad when this Hurricane passes so I can check on my motorhome.
FWIW, I only peel the corners off so the only parts exposed are four corners (most of the pass still has the protective backing on it) and it comes off pretty easy like that and seems to work fine.
Having said that, when I bought ours (about 10 years ago), they only had the sticky and a really big battery version with lights on it for $40 or something like that. Now that they have the Minis, it's probably not worth the hassle and just get a mini. If nothing else, we have a sticky in our motorhome and a sticky in our car and when the motorhome is towing the car, we get double charges so have to contact them to get it corrected. With a proper removable one (i.e. a Mini), we could just transfer it from the mh to the car as required.
