I think there used to be an issue with cracking some time ago but they supposedly fixed it. Got mine new in March and have had it off and on a few times and it seems perfectly pliable so far. The clamps they provide are way overkill and it wouldn't be hard to over press the rubber boots. I'm not really sure they're even necessary at all. Just the slightest pressure from a tie-wrap would be plenty especially if you keep the bear claw cover.
Sorry for your problem but i'm certain they will take care of it. I talked to them about why they aren't selling or advertising the recharge oil and they were very responsive. Of course they haven't changed their marketing a bit? I think it would be to their advantage, but maybe they don't want to bring up any maintenance issues or the fact that it does have to be cleaned occasionally?
