Super Easy Pick
Bought this to practice lock picking, was in within less than a minute. Only have to pick one of the 4 pins. Not secure at all, there are much better options.

NOT weather resistant!!
Used this lock to keep a storage locker secure which in fairness it DID do. HOWEVER when trying to remove it, each key failed to turn it even a little and a slight jostle of the lock had water dripping freely from the lock.
Be sure that if you want it to come off, you also have access to an angle grinder and a metal disc.

This product is really average, or moderately worse than that. However to be fair, such quality is very fitting for the reputation of master lock.
All disc padlock really offer very similar resistance to twist attacks by pipe wrenches and cut attacks by bolt cutter, mainly by the virtue of being disc padlocks.
So the difference really is on the resistance to picking. On this matter, master lock is very consistent to its reputation by offering very average or moderately worse performance. If you could afford 50% more, get Abus diskus padlocks such as Abus 28/70 diskus padlocks. If you want extremely high pick resistance, get Abus diskus plus with the Abus plus cores.
In contrast, I wish to be fair to point out the very limited utility to have extremely high pick resistance while there are other ways to destroy disc padlocks. Examples would include an angle grinder.
Thus, in my view, Abus diskus plus padlocks are overkillers for normal applications such as storage unit padlocks. One would choose between MASTER LOCK padlocks and Abus diskus padlocks, depending on one's applications.
