The lock looks solid, is heavy, has a nice bright yellow color, which is conspicuous on the dial, for me the function of selecting the lock with or without an alarm is important and useful, it works well.
The alarm itself is quite loud and performs its function. I recommend.
It is worth spending a few zlotys more and be sure that a possible thief will be surprised - because Ulock looks very ordinary, and the volume is appropriate alarm. I recommend
Solid reminder. Doesn't tear, doesn't discolor, returns to its shape after stretching, highly visible. Cheaper than repairing the damage after moving with the blockade.
