"Had 3 of these replaced having been locked out by them and had to cut them off. Screwfix were very good, no questions asked but we gave up and asked for our money back after the 3rd time. Nicely built lock but no use if it locks you out! They lasted about a month each and it was of great inconvenience when they failed. Spoke to a locksmith about these locks and he said they have a lot of problems with all Squire combination locks, their key locks are fine though. Even when they did work, the mechanism didn't feel reassuring and you often had to 'jiggle' the keys about or pull and push on the lock. Bought an ABUS combination lock which has been no trouble."
