I've been using the rim blades for a while and really liking them. I've installed them a few times as I traded in my car (two sets) and I have them on winter wheels too. When I had the TPMS replaced on the winters the garage managed to ruin the rimblades in the process so I had to install them again. Also I've had them damaged from a couple of kerbs and replaced them accordingly. I bought an extra kit (kit does 4 wheels) so I can replace individual wheels if I need to. I have found if I hit something hard enough it is still possible to damage the wheels but they have definitely saved me a couple of times. On my winters, I just replaced the rimblades on one wheel which hid the damage anyway. I'll eventually fix it but for now the wheels still look great. As I've never tried the alloygators I can't say if they offer more protection in harder impacts or not. I"m interested to hear comparisons.
