Good construction but it is heavy and the key doesn't fit well, it needs a little movement to find it. Otherwise, it is secure. It definitely deters thieves as it requires a wheel to be cut. I use it on my scooter along with another one from a different brand and I leave it outside for a while without worrying about it being stolen. For example, for supermarkets, etc

Definitely very sturdy, but heavy and bulky. I struggled to find a place on the bike for the stand so that it wouldn't bother me. It's worth it for a very expensive bike.

good quality.
