Has anybody found a 4.5+ft chain that would work with this lock?
I ordered the OKG Heavy Duty Security Chain but the the chain links are too small for this lock's shankle.

This bike lock is exactly what I look for, good high quality material, U type lock, heavy duty and combination lock. Sad they don't sell this anymore as I would like to get more.

Bought the lock because of the combination locking system which means no keys to fumble with or loose. A friend had this lock and he was happy with it so I thought I would give it a try. Its easy to operate and it is secure. I am happy with my purchase as it works great with my E-Scooter.

It's been working well for years, not easy to find a U-lock with a code! I don't carry keys with me, I'm all about the codes, this works.

Only gripe at all is that it would be nice if it were available in a version 2 inches longer to reach around my Mtn bike front tire so as not to need cable also. This is very quick in terms of locking and unlocking. I have a rack bag on the back of the bike, so when not in use, lock sits perfectly along the inside base of the the rack bag and actually serves to stabilize the bag. Yes its a little heavy, but it definitely will intimidate most would-be thieves. Code is easy to set, and this is great because I hate carrying around extra keys.

UPDATE: I was sent a replacement lock and Daisy from Amazer was so kind and helpful during this process. Th lock came in fast, is longer, and has an area where you can securely attach it to your bike while you are riding it. I have not tried that yet, but maybe soon.
I still don't love this lock as much as my Kryptonite lock, but Kryptonite is much much more expensive. The long look is nice but it still doesn't fit quite right around my tire and my base. There is still a combination lock, which may still be the same issue in regards to it breaking the first time, but I know it is sturdy and it is much easier not having to carry around a key. That is something I really like about this lock.
Overall a good and standard lock. I know they are working to improve their stuff and I appreciate all of the help I have gotten.
Past Review: I bought a much more expensive lock, because this shredded to pieces when I couldn't take it off at school one day. I really liked the combo lock aspect and not having to use a key, but one hit and this thing comes off like a piece of cake.
Kept my bike safe for a year in a moderate-high crime college campus,...

A very good lock. It works great. No keys! It is a little bit smaller than some U-locks out there, but good price and also the combo code is easy to dial quickly. **Kudos to this company b/c they sent me a second lock at no charge to me bc (whether I screwed up setting the combo or something went wrong with the lock) I made it to where my first lock would not open with the code I THOUGHT that I had set. There is a note about using a simple code like 0001 to test it, but it is below the intructions and after one might have already messed up the combo. I really like this product. Make me feel my bike is a bit sager than with just a cable.

Very solid unit, I like the code system better than key entry, like that it can secure my bike at a bike stand large diameter pipe. However, the downside is the mechanical operation is subject to failure (jamming), Purchased 3 yrs ago, very happy with its performance & operation until today removed bike from rack and closed lock, attempting to reopen to secure my bike again lock would not reopen, I tried every solution attempting reset, oiling the mechanism NO success. it would appear the lock has jammed the reset lever and many adjustments of the combo has not alleviated the condition. Having owned and used the unit for 3yrs, I am disappointed at the failure but will replace with another Amazer unit in the hope that they have eliminated this anomaly.
