Plastic cap broken upon arrival

I'm sure the lock is fine: big and chunky bolt that goes through the gaps in the brake discs, but the black plastic cap is a waste of time - was broken in the packet when it arrived. I'd probably buy a different one if looking again.

Quick, additional deterrent

I chose the 10mm pin as my disc brake will take it. It is fitted in seconds - slide it on and push pin down to lock. I squirted a bit of WD40 (as tipped by another customer) which made the pin release a little more easily. The plastic weather cap fell off after 2 days of use but the carry pouch helps to avoid dirty smudges when pocketed after release. Good value for money as a quick, extra deterrent. Also have a chunky chain lock for more substantial security.

Strong little detterent

Brought this for my new 125cc bike and will be using it with my chain lock . May not be very strong to stand any stealing attempt but will be good deterrent. I use it a handy little lock when I go for quick shopping

Neat but a little fiddly

Benefit of the doubt 4*, this thing is quite nice and compact (6mm),and I like the plastic weather cap. On mine the lock is a bit fiddly to get it to release though, but perhaps that's a knack thing. Comes with a little canvas pouch with a belt loop/small strap combination so you could attach it to the bike somewhere, but the velcro fastener isn't mega secure.

Mammoth disc lock

The mammoth disc lock is simple to use and does what it's supposed to. It isn't fancy with alarms or anything but a simple solid well made lock that is fairly priced. It comes with a handy carry bag so all in all I am satisfied with it and have no complaints

Decent kit and does the job. Easy to get on and off the discs and never gives me and fuss like some disc locks can do. Recommend.

Good Disc Lock

Good solid lock for the money. Handy to carry in the jacket pocket or top box. Bright colour and comes with it's own little pouch to keep it in. Paired mine with a slinky type lock reminder to avoid trying to ride off without removing the lock.

Does what it says on the tin. Delivery was fast as always from Sportsbikeshop. Excellent deterrent for the price, like other reviews cap is a bit flimsy but I'm extra careful and haven't lost mine yet even tho it's popped of a couple times lol.

Handy little lock

Easy to transport. Good value for money. Just remember its on the bike before you set off!

Cheap and cheerful

For the money this lock does the job as an extra deterrent. It's very visible and seems strong. Only slight issue is it can be a little difficult to unlock at times just because the key doesn't always match up correctly inside the lock. This would be the only indication that it's not a top end price lock. Worth spending the money for an extra bit of piece of mind.

Works but fragile

The lock bit works OK, but the key-hole cover snapped off the first time it was used, but it still works.

Peace of Mind

Solid little lock that is an ideal deterrent. As others report the mechanism is a bit stiff to start with but a small dose of oil fixed that, and the plastic cover over the lock disappeared after a couple of uses. I added a reminder cable and use the disc lock whenever the bike is parked up.
