I am not very good at managing my ever-growing collection of keys
I am not very good at managing my ever-growing collection of keys. I have a box full that I'm not sure even fit any locks in my home anymore. Needing some new secure locks for a household move made me think about these - four very secure locks with identical keys. Each lock comes with two, so I now have eight keys to add to my collection!The locks themselves are pretty tough. The shackle is thicker than most locks, so be sure that your clasp will handle it - but there is so little shackle visible that it would be tough for some jerk with a bolt cutter to get to it. Nice job, Master. The locks are a little stiff to open and close, but not a nuisance.

Worked Great ! worth it !
Needed these for a utility trailer WORKED GREAT, all keyed alike which means one key will open all four, no need to have 4 extra keys on an already filled up key ring. Operation was smooth and they're strong enough for the job. Stainless Steel is a big plus since it's outdoors. If you find you need more with the same key, use the key code to ensure you buy more locks without having to get different keys, you always find use for more locks as you can lock up individual equipment. Multiple deterrents are always a plus in helping to keep your items secure. Make sure to use graphite lock lube NOT ANY OTHER LUBE in order to keep them operating smooth.

Top quality and virtually indestructible
Keeps your stuff secure ,a thief would make so much noise trying to beat these off the whole world would know what's going on. And they are all keyed the same that's a real plus in my book

Made in China!!
I've been using these locks forever. This latest bunch just doesn't seem as sturdy or well made as the ones in the past, like they're "loose" or "sloppy" if that makes sense. 5 stars to the seller, I bought 8 locks, keyed alike, and each of the 2 keys included opened each of the 8 locks. Yes, I checked every one.

Secure locks that work great.
I bought a 4 pack of these locks a few weeks ago for my outdoor sheds. It's really great to only have to carry one key to be able to access all the sheds. So far these locks are working great. No problems.

Heavy duty
Good locks. Heavy duty. Only problem I found is after snow or rain they fill up with water and freeze solid. Impossible to open until I get them thawed out

Good quality locks keyed alike!
Amazon wants me to rate these locks for "sheerness" and "warmth". Rated them at 5 stars, though they are neither sheer nor warm... The locks function smoothly and fit my trailers perfectly. Now If I can just another 4 pack with the same key number...
