Super outdoor padlock
I bought this for my garden gate and I’ve had this for a month now and it’s rained pretty much every day and so far no sign of rust. I added a little WD40 when I first put it outside so that might have helped. It’s very easy to open and lock. So far I’ve no complaints and for me great value for money

Smooth Action
Super lock, smooth easy open and lock. Super having 4 keys as we both have a set. Bearing up well to recent frost and rain. Does the job securing our sidegate. Will update in 12months on durability.

Good, works fine
A padlock for locking things up, I tried to lock up my wife from shopping all the time, but she wasn't having any of if. This has been on a chain outside for the last few months and been fine. It did go dry and stiffened up but a drop of oil sorted that.

Strong Looking
Recipient was very pleased with this padlock. Used on bolt to secure side gate that is reasonably sheltered from direct rain. Was well oiled before being fitted. Key operation remains smooth after a few weeks outside.

Study
Now that’s a sturdy lock. Bought to replace default lock that has seen better days, and was 50% rust, and hard to open and close. This one is weighty, sturdy, and looks easier to maintain.

Not even basic security against picking

Got this for my daughter to keep her safe. It is perfectly hefty enough to do so.

Preso la taglia M. Arriva con 4 chiavi come descritto. Sembra davvero robusto. Ho notato che ogni tanto (2volte su 30) fa fatica la chiave ad entrare, magari perchè l ho usato poco.

Sehr geehrte Damen und Herren, heute beim Aufschließen brach der Schlüssel ab. Ich war ausgesperrt. Wie kann das sein bei der Qualität? Ich erwarte Ihre Antwort. Mit freundlichen Grüßen S. Lenz
