Solid heavy chain. Good quality D-lock
Solid bit of kit. The D-Lock is a good size as well. Easy to pop in your bag and use on it's own if you didn't want to take the chain with you.

Very heavy lock & Chain
Very heavy lock & chainWell made and seems very secureMore suited to stationary location as it would be too heavy to be portableGreat length the 1.5 m version fits round the motorbike seat and through the rear wheel 👍

Very heavy chain and lock
I use it as extra security in my garage as is very heavy so I would recommend using it as base security rather than carrying it with you. I use it on my scooter. Very good quality chain and lock at a reasonable price.

Absolutely solid
Solid lock and chain, with a good length to allow lashing to almost any fixed item including telephone poles. I keep mine as my home lock system as its huge and heavy and I don't want to carry it on the bike.Please note UK insurance companies do not recognise the make or model despite the sold secure rating. Some say locks don't affect your premium but I don't know, they wanted the details and recognised the anchor and disk lock I'm using and wanted loads of details on my garage for a reason I'm sure.

Quality heavy lock and chain
Great quality heavy lock. Looks like it's indestructible. Hopefully it is if ever the time comes.

Better to have it and not need it
Love the Appearance , length ,ease of use, fitband weight( just thinking of a way to carry it around). I am the proud owner of this product, and use it along with Litelock Core , Litelock 1, disc lock and tracker. Might seem like overkill, but don’t wish to chance it.Having had my previous bike stolen I am now of the opinion “Better to have lots of security than only have the minimal , then have your pride and joy taken.

It's Heavy!
Until someone tries to cut, or cuts the lock and chain it's difficult to know if it's fit for purpose. However, both chain and lock are substantial so best used at home or left where you need to secure something as you don't want to be carrying it for long. I'm using with a ground anchor, so pass the chain around, back though the loop and through ground anchor to secure with lock. The lock is easy to lock/unlock with key (4pcs).

Heavy but secure
I use this for my £3,500 e-bike in London. It’s very heavy but it’s the Boss! Use it or lose it!
