Actually the ZooMed units have a warning on the box not to remove them once attached..
Oops... that is probably for warranty purposes...but I'm not doubting you...you definitly know more about them than me. I'll admit that I have done this and had no problems with them (one I have had for over two years and I have moved it around at least twice), but if Matt says not to your best bet would be to not do it.
