Rusted shut in one semester

Rusted shut in one semester
I’ve had this lock for nearly 6 months and I’ve had to have it cut off my bike due to the lock rusting shut. The key would get stuck at around the 45 degree position (where the mechanism actually starts turning the lock) and not budge, even after drowning it in WD40 and machine lube. The inside of the lock is covered in rust and the key has been chipped just from inserting it into the lock multiple times a day. The lock and key also have a defect where you need to fiddle with the key to get it to fit in all the way. At the same time I’ve had the arms of the lock come out while I was biking, and the whole thing has popped out and slid to the side while biking before. The plastic frame also dented where the screw was screwed in, with the screw initially imbedding itself in the plastic.Tl:Dr if you get this lock, it’s convenient, but doesn’t resist rain or ice well, and also carry a small hammer to help with opening the lock, a good wack While in the 45 position should be enough to seat it all the way inside.
Thank you for your feedback

5.0 out of 5 stars So convenient
Reviewed in the United States on June 9, 2023
So far, very satisfied with this lock. I don’t have a quick release on my front tire, and the lock fits perfectly under the seat post for locking on the rear tire. I also found the screws not long enough for the bottle cage to be on top of the lock, but I didn’t need it anyway. Very slight rattling, just need to be sure it’s snapped in place before riding. My only complaint is that the locking mechanism itself seems a little loose. As others have mentioned, you have to find the sweet spot to get the key in to turn. Overall, the sleek fit and convenience wins out.
