Review: Solid and Reliable Lock — Worth the Price - My husband said it Feels really sturdy and well built. The lock mechanism is smooth and doesn’t jam like cheaper ones he's used. It’s got a good weight to it without being bulky to carry. It gives him confidence leaving his bike locked up. A proper bit of kit if you want security and peace of mind.
Review: Feels secure and reliable, worth the extra weight - This is a seriously solid lock that gives you a real sense of security. The U lock alone is thick, heavy, and feels virtually tamper-proof. The included flex cable is a great addition, giving you more options to loop through your wheels or around awkward railings or posts. I’ve used it to lock both my frame and rear wheel with the U lock and then looped the cable through the front wheel. That versatility makes a big difference in urban areas where secure anchor points aren’t always ideal. While it is heavier than cheaper alternatives, the added weight feels justified by the protection it offers. I’d much rather carry a little extra bulk than come back to a missing bike. The lock mechanism is smooth, and the key turns easily without sticking, which I appreciate after past frustrations with cheaper locks. Pros: Heavy-duty and high quality Flexible locking options with included cable Smooth key operation Cons: A bit bulky for smaller backpacks It might be overkill for low-crime areas

### ⭐⭐⭐⭐ Cost effective Sold Secure Silver lock
*by P***L on 1 August 2016*

I purchased this to leave at the office, so I don't have to drag my lock back and forth. It is a pretty standard 'D' lock, with a short (4 foot) cable. It has a handy velcro loop to tidy up the cable into a loop. It comes with two keys and a bracket to attach it to your bike (which I have not used). This is the KryptoLok Series 2, it is part of the Sold Secure range, at the Silver level (NOTE: the cable isn't recognised as Sold Secure and could be easily cut, it will only help prevent somebody pinching your wheels). Sold Secure Silver level offers enhanced security, but with cost compromises from the highest level (Gold) and often lower weight than Gold. Bronze is only recommended to stop opportunist theft. If you need a secure cable, there are Silver and Gold options on offer. The replacement guarantee from Kryptonite is full of weasel words and reading through it I decided I would almost certainly not get my money back in the event of a theft. The limit is £800 in the UK for reference. In use the lock works well and I can bolt my frame securely and protect my wheels with the cable. I cannot get the lock around the fence post (looks like a scaffold pole diameter) and through both the rear wheel and the frame. The lock mechanism works well and is easy to unlock, unlike some I own. I thread one end of the cable through a wheel, through an eyelet and then round the other wheel and put the loop into the D lock before I close it. I ride a 20" mountain bike frame on 26" rims, but if you have something with a longer wheel base, you might find that 4 feet is too short. All in all, I am happy with the purchase. I knew the guarantee would be almost worthless, but it's a decent lock and protects my cheap unfashionable bike in a low risk environment. I would not use this to leave my bike in a public place all day e.g. rail station, bike racks at school, etc. You'd want Gold for that.
