Rated 1 out of 5 Do not buy this lock! Bought this lock a couple of days ago. I reset the combination as per the manufacturers instructions and tested that the new combination worked, all good! :-) I fitted the lock to a garden storage box and again checked that the combination was working. Came to it the following day & the combination wasn't working ...I've since spent the best part of an hour drilling through the combination part of the lock to release it. Needless to say it is going back to Master Lock. Stick with Yale ....alot better quality. 7 Nov 2015
Rated 4 out of 5 by Half half For a higher spec and priced padlock (all weather) I am surprised the cap over the numerals appears to be more of an afterthought than a carefully thought out element of the design. Rubber cap, rubber hinge pins... the darn thing falls off so easily and is fiddly to restore. Agreeing with other user that the tumblers can be tricky to manage with cold wet fingers. The rest of the lock appears to be sturdy quality, tho' I haven't had the need to fully test it by cutting it off. 25 Aug 2015
Rated 5 out of 5 by Good value product Seems to be a good solid lock and found dials easy to use. Like the fact that dials are hidden by cap. Good product 6 Aug 2015
Rated 1 out of 5 by Returned for replacement The padlock had to be returned and replaced for a different model as the lock would not open on the 0-0-0-0 for us to re-set the code. Happy with new purchase. 16 Apr 2015
