Bought a 2nd bike so got the same lock - never had an attempted theft, but easy to use and portable.
Good value

Very good lock which includes a reminder lead. Lock is slightly fiddly to get the key in but not a deal breaker.

Well made, good value lock
Useful security
25 November 2018 by Darren
Not much about it that's mini but it does fit under my seat and comes with a belt carry pouch if required. Very sturdy with useful reminder tether. Easy to use as the shackle detaches completely for fitting. Great value for a Thatcham approved lock which also reduces my insurance premium. Recommended.
Good value, key fiddly

Great sturdy, fits anything lock but the keys take some effort to go all the way in so as to turn and lock/unlock, which is a pain.
Good Value lock

Appears robust and is easy to fit. Unlocking is also straightforward (unlike another similar devise I use|) which is very welcome, and for that reason I'm happy to use it without hesitation every time I park.
Seems good quality

A bit larger than expected but seems good quality. Easy to lock/unlock and good to get case and three keys.
Great item, looks sturdy and well made

Great piece of kit. Strong and sturdy I would certainly recommend.
Good solid lock
29 August 2018 by Stuart W
Feels very solid, used it every day for last month and can't fault it. Big enough to be seen on the bike and it will also fit in my leather jacket pocket, quite heavy though, which is probably a good thing. First disc lock I've ever used and I'm very pleased with it.
Good security for the price

Solid looking disc lock as a back-up security feature. Fits in a jacket pocket and comes with tether to ensure you don't forget it's on. Reasonably priced too. Would recommend.
Easy to lock

As I said easy to lock and unlock. Solid, well made and can also be used with chain without marking the paintwork. Also stows away under the seat with no problem, very pleased with price and product.
Nice lock

Excellent disc lock, Thatcham approved. Looks too big for bolt croppers. No problems with locking or unlocking. Not much more to say.
Very good value

Very good value. Feels substantial for the size and the money, fits easily onto my CBR500R, and small enough to be stored underneath the pillion seat.
Only minor problem I have with it is the key, which can sometimes be quite awkward to use with the lock.
Very good for the price

Feels well made and solid and fits easily through the front disc on my 99 VFR. Would be 5 stars but the the key is sometimes fiddly to get in to the lock.
Great product, excellent value

This U-Disc Lock is strong, feels solid and fits to my XT660Z's discs or rear sprocket with ease. Inserting the key can be fiddly sometimes but not an issue. For what it costs, I would definitely recommend this product.
Great product, excellent value.

Great product, excellent value for money. This is a strong sturdy disc lock and it is easily as good as those costing twice as much.
