My great grandpa used to be obsessed over these. Every night he would have his nightly routine that involved going outside to check the shed and the basement (it was on the outside.) One night someone tried breaking the shed lock and of course it didn't work. These are pricer, but super heavy duty!

These little guys are strong for home. I use them to put on things like my little shed. They are durable and don't rust as easy. They come with two sets of keys so if you misplace one you have an extra on hand.

I bought this padlock to lock up my money and important information. It's a solid heavy duty lock. I trust that this padlock will keep my items safe and untouched. I definitely would recommend this to anyone.

These pad locks are one of my favorite they are easy to use that hard to break. They are very effective I haven't had any disappointing factors. They are a little bit more expensive but not too much more and I would definitely recommend

I have this lock for my gate. I would re buy this. It never gave me any problems. The keys always fit. It's not hard to latch or unlatch. It's affordable for sure. I recommend this lock.

Heavy duty and reliable are the thugs I would have to say about this lock. I like that I can lock something up with one of these and feel pretty secure about no one getting into my stuff.

This lock was great, and pretty strong. I used it for my trunk/footlocker in college. It withstood my drunk roommate trying to pick it/break it off when she was looking for food. I would recommend this for smaller boxes or trunks only.

I use this lock to lock my switch box that is located outside my house. I hear people can easily switch off your power so someone told me to get a good lock.

When I am purchasing a lock I always choose master lock. They work well and last forever. They are reasonably priced and always come with at least two keys.

These are great. I have them on my sheds. No problems whatsoever. No need in remembering a combination code, just have to remember where we put the keys!
