Goldi locks
Great Locks! I leave them out in the rain and snow, and they always work. Get as many as you can with the same key, so you don't have to carry a big wad of keys around.

it's the very best lock I've found for my needs
I have a beach house in Baja which is in a remote area and completely off-grid. I've used a number of different types of locks over the years to secure the house while I'm gone, but have experienced 2 break-ins nonetheless...until using these locks. These locks are virtually bullet proof. As mentioned above, I've had no break-ins since using these locks. They also hold up well to the marine environment. Keep in mind, though, nothing metallic will hold up indefinitely to the salt air right on the beach. I replace mine as corrosion becomes evident, which is every year and a half or so. That being said, it's the very best lock I've found for my needs. To top it off, customer service is excellent and timely. This is a great product sold by a great company!

They rust very easily
Still a super durable lock but these are stainless and shouldn’t corrode.

Very large and solid
Measurements are accurate. Works perfectly for a large motorcycle style heavy security chain. Action is smooth, and keys are cut precisely. Haven't used in the wild yet, but fit test was perfect.

I am (pleasantly) surprised
I ordered two packs for a total of eight of these locks. I emailed seller to verify all locks would indeed be keyed alike. I was surprised when my email was answered in a matter of minutes even though in my opinion the timing of the reply was outside normal business hours. I was also surprised when after placing my order, my package arrived *before* the promised due date. WOW!! All locks were keyed alike per the request and seller's promise. Again, WOW!! As I complete my project, as I need more things this seller can provide, I will check with them first. Thank you!! As for the product, it is a great item, tougher than nails or any other padlock I have used before.
