Good chain, padlock not so much

Chain is good and solid but the padlock feels very light and flimsy.

Good chain

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.

Home Security

Good strong chain, not much more to say really, it does what it's meant to!

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 length, strong feeling chain

Chain is a good enough length to get around what you need to. Strong looking chain that will probably make thieves look for an easier bike to steal. The lock isn't perfect but has a smooth operation.

Happy, chain and lock look and feel strong

Lock and chain look and feel strong and will hopefully deter all but the most determined thief. Recommended.

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.

Essential purchase

Does exactly what it says on the tin. This is a mammoth of a chain will keep your bike secure.

Mammoth bargain

Does exactly what it says on the tin. Robust heavy chain with a protective sleeve. Heavy duty padlock with a slide over lock cover to keep the rain out. Good value for the money.

Good chain and lock

Good value strong chain and lock, long enough to go round a post and wheel. It is heavy, hopefully will deter thieves.

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!

Good, basic chain

Not too heavy (getting carried around in Vespa underseat box), together with a disc lock. Hopefully thief-retardant enough.

Strong and light

Very strong and long enough to go through the frame and both wheels of my bicycle. Surprisingly light, but need a strong bag to carry it.

Very strong lock

I wanted something strong to deter any would be thieves and it fits the bill. However it is very heavy and takes up quite a bit of storage in my small scooter but on the whole well worth the money.
