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

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.

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.

Cheap and cheerful

OK its cheap, not the best in the world but for the price and for what I needed it for (as a visual deterrent) it does the job. The lock is a bit sticky but lube it up and its fine. Comes with 2 keys and a pouch and has a nice bright colour.

Cheap, original and strong

Simply brilliant, you can pop it on the bike anywhere you go and the colour is good so it's noticeable to you and others so people will think twice.

Cheap deterrent

I just wanted a cheap deterrent and my new insurance requires some type of lock. This fitted the bill. I went for the 10mm partly because it had the rain cover but this popped off a few times after a light touch and eventually jumped into a pile of leaves never to be seen again, (hopefully regular oiling will do the job). I always presumed the pin went through the cooling holes in the disc but it turns out they fit through the inner part of the whole disc. Unfortunately my rear wheel cannot be used for this reason.

Good lock, great value

One issue, noticed by others I think - when first trying to insert / turn the key, it was tricky and took patience. However, after adding a couple of drops of oil, it's noticeably better and works fine.
