Review on 1561DLTBLU Locker Lock Combination Padlock by Master Lock - Light Blue (1 Pack) by Steve French

I don't trust these locks. Revain was great in that it replaced the first lock I got which didn't always work, sometimes it took many, many tries. I would give Revain 5 stars but the castle is 1 star. If I could I would give it a 0. Note that the reason I wouldn't trust Master Lock is because I also got 2 more Master Locks from Walmart today (total of 3 locks were required). Walmart's master locks didn't work either. What is the probability that out of 4 locks only 1 will work I don't know how these items can sit on the shelf, that's a really high failure rate. Is there quality control.
