Mammoth Security 10mm Square Lock & Chain
Customer Product Reviews
Good heavy duty chain, and a really good length for getting around what it needs to. My only issue is the lock itself, I have had a few Mammoth products, and they all require me to 'jiggle' the keys to locate it properly. Nothing major, just a very mild inconvenience.
Seems up to the job
Chain is very solid, cover is well attached. Lock easy enough to get on and off, keys also seem sturdy. The peace of mind this offers is what I like. Obviously I would hope it's never put to the test, but I feel better having it on the bike.
Good for the price
I like the length and weight of this chain, but not convinced by the lock, which doesn't look like it would put up much of a fight to a set of bolt cutters. Also, though I haven't had it on and off the bike very often I've noticed the protective sleeve in the chain is already wearing through. Overall, not a bad addition to the other security measures I have in place and no doubt a good deterrent to any passing opportunist thieves (hopefully). Also a good price compared to other similar products. I'm not sure I'd totally trust my bike to this lock and chain on its own though.
Big chain, feel safe, one flaw...
Fantastic chain, it's such a thick metal I doubt the thieving little toe rags can get through this! I would give it 5 however there is a vital flaw, trying to lock it is a nightmare. You have to have a technique to lock it up, its not as easy as put in the U lock and done, it's put U lock in jiggle use a choice of vulgar words and then be amazed as to how you got it to lock!
