Review on 🔐 CATALYST 200 Pocket U-Lock - Silver: Superior Security for Bikes by Dee Parson

At first glance, this U-lock looks very good, it does exactly what it's supposed to. However when I tried to unlock it last week it was very difficult - the key didn't fully turn for some time. I thought it might have gotten wet so I dried it out, cleaned the inside and kept using it. Eventually it got to the point where it wouldn't open at all and now it's just stuck permanently and won't open. The key does not work, does not turn completely. WD-40 and many cleaners were useless. I am currently using a friend's padlock until I find out or buy a new one.
