I gave this look 4 stars because the keyway and key alignment is very difficult if the lock is subjected to vibration or movement. without laying on the ground and looking up into the keyway, it can take several minutes for the key to engage the tumblers.
Other than that, the lock is so robust and well-made that the bad guy would have to cut the entire front of the A-frame off and bolt a new one in place to defeat this lock!! Fit and finish are excellent and there is no doubt that this is the toughest lock on the market. I would not hesitate to buy again. My experience with Altor; A real human answered the phone and all of my questions!!! Polite, professional and very knowledgeable of the product. There is no tougher lock out there, I looked at them all!
I think that the only modification would be for Altor to introduce some "Drag" into the keyway entry point so that it does not move so much under vibration.
Once I opened the box and seen this lock I knew I would not worry about someone cutting this lock off and taking my trailer. 5 Star engineering!
I spent quite some time on the web to find a hitch lock to protect our investment and I initially bought a cheaper hitch lock but wasn't satisfied with it. I then came across Altor locks and after reviewing the videos I thought I would give it a try. When I received the product (within a few days!), I was blown away by the quality and toughness of the product. Now, THIS is a lock ! I obviously don't want anyone to try stealing our trailer but I feel much safer than with the previous lock !
The customer service is also very nice: less than a week after I purchased the hitch lock on the Altor website, they had a special offer including a free carrying tote for each hitch lock purchased. I reached out to them to check if they were willing to do something about the carrying tote and they quickly replied to me that they would be very glad to indulge me since they really want their customers to be satisfied. I can't wait to receive it but thank you already Altor for your kind gesture !
Highly recommended !

Ordered the Double Apex Steel.
Thoroughly impressed.
The locks are wonderful, easy to use, and fold up to ‘nothing’- they’re very convenient to ride with.
The Altor Team was super responsive and easy to connect with.
110% recommended!

Fits perfect and helps it not roll around when not on the trailer. Feels like I’m caring around a bowling bag lol. Great product to keep your lock secure during travel or when not in use.

I received my lock on-time, and in good condition, however it arrived in advance of my e-bike. I cannot fully review / critique how well the lock works until it is actually deployed and in-action. I am confident thieves in the know will stay away from this portable grinder destroying lock.

Great lock. Deters people from attempting to steal it. Gets the job done.

I ordered the SAF 2516 late at night and it was shipped by like 10:30 the following morning. It is a beast and I can now leave my camper and rest easy. This thing is a beast. Altor sent multiple keys as well. Very impressed.

This has to be one of the heaviest and most secure locks you can buy . It’s a industry BEST!!! A must have for the world we live in today . Way to hard for any advance criminal, if your getting through this lock it’s going to take days. Absolutely will buy again thank you

After years of owning a different, yet popular airstream hitch, I like this one much better. Living in the South, the other popular brand had enough opening that wasps were a common issue (getting in it and building a nest). Will not be an issue with this lock. The bag is a nice to have as well.

This is awesome. We feel more secure with this lock. We researched several and decided on the Altor. It’s expensive but we need to protect our trailer so well worth the cost in my opinion.

The quality and peace of mind that comes with this lock is hard to put a price on. It keeps my airstream safe and sound. Big fan!

It was a little expensive but we'll worth the money.

My trailer is parked outside and makes me a little nervous knowing someone could hitch it up and take it away while I'm in bed. Sleeping easier now knowing there's not a chance.
