Well built. Seems very secure. Lock itself could be more beefy, its made of aluminum.
Solid lock. Fits the hitch on my Airstream perfectly.

RETURN CUSTOMER - QUALITY PRODUCT
Purchased a PROVEN trailer tongue lock this spring for our camper trailer and was so impressed with the DESIGN & QUALITY that I ordered a second one for another trailer. They are more expensive than cheap imported knockoffs but when I leave the trailer parked I am confident that thieves would look for an easier target.

totally tough and has the metal to prove it
Game changer tool/ accessory. If you really want to secure what's important, this is the one! Our airstream at least has a fighting chance at not getting hauled away by someone who's not us. It is easy to use, very cool looking (and therefore seems pretty boss-like at first glance), hefty and the 'look' of it shows it means business. Hard to find a lock that isnt easy to break. This one is the best we've found. $$ but the peace of mind is so worth it.

This is the best coupler lock on the market today.
This is the best lock housing for a hitch coupler out there at this time. This is for my 1985 Airstream Sovereign (Remod) and it is an absolute beast. It’s expensive. But a missing trailer is worse and more expensive. The heart ache alone is worth the money. Get a GOOD puck lock and do your research since there are many choices and all have their vulnerabilities. YouTube has many videos of locks failing so you can make a wise choice. This model of coupler lock will NOT store your safety chains. And this is a problem since some thefts have occurred by the thieves hooking up the chains only and driving off with the trailer. But this gets harder to do the larger the trailer. Look into adding an internal GPS tracker so should your trailer wander off on its own you can send the police to its exact location. This too in my opinion is worth it in peace of mind. In a nutshell, I am very happy with this lock and do not believe a better choice exists. Buy this. Now go get a really good puck lock. And a GPS tracker. And maybe a HD padlock for the safety chains. Or make the chains removable. Some have added a wheel lock. Thieves are expensive.... :(

Good customer service
Fit our 2016 Airstream International like a glove. Looks solid & well made. Didn’t see instructions in box but was easy to figure out. It was pricey but a lot cheaper than having your trailer and possessions stolen!

The best trailer hitch lock available.
Very strong and solid lock. A thief would need a powered cutter with ample time go remove it not to mention the noise. The safety chains can be wrapped around the trailer tongue and the hooks locked inside the lock housing.
