very good quality - and quite strong, easy to change settings and open is a little heavier than I though but that makes it look VERY strong

Seized and had to be cut off
Used this on an outdoor bike shed, in a sheltered location. Occasional use only. After just over a year, it locked shut - the wheels could not be moved individually, they were all locked together. I had to get the angle grinder out and cut it off. Brand recognition led me astray - waste of money.

feels heavy duty, like it has some weight to it. roller can be a little tricky but overall, I think it's a good lock. my only complaint is the little rubber cover on the bottom does not stay on very well. would buy again

Solid lock that has held up for 2 winters, through rain, hail and snow. No sign of rust yet.

Se ve de buena calidad, ya lo empezamos a usar y está excelente, eso sí, no le entiendo porqué tiene una cosa de plástico abajo si se cae a la primera, no entiendo cual es la función o el deber ser.

Using this on a storage locker. No problems so far. The rain cover seems a little flimsy but still intact after 6 months. But the lock itself is very sturdy.
