Fit for purpose, easy to use and is priced reasonably. Is also visible which should act as a deterrent.Would prefer a combination lock (one less key to carry around.

A friend of mine had had his camper trailer stolen off the back of his ute so I bought a coupling lock for my boat straight away. Should deter all but the most determined crooks. It locks the trailer on its own, or locks the trailer to the car. Recommended.

I had the previous version with the single position slot and while I might not use while travelling, I thought it was a good feature should I ever want to. The supplied lock provided doesn’t feel the greatest so I will probably swap it out for a better one.
Good and bad experience...Good: I managed to lose the keys to the padlock but it was super easy to lever the padlock off.Bad: It was super easy to lever the padlock off.
Not great doesn't sit tight onto the boat trailer tow point and struggled to open the lock first and only attempt at doing so, required WD40 to uncease, only been on for 2 months
Trailer lock does it's job but the padlock rusts too quickly, it needed WD40 within the first month, plus also Bunnings can't cut keys more most padlocks and I had to go to Mr Minit.
Lock it self is good but the padlock that comes with is already showing signs of rust after 3days of use and was hard to remove. I'll replace the padlock with a quality product.
This design has been around for years. Nothing more to be said here on that. But coming with the padlock for this price is hard to go past.
Good version of this type of lock. A step up from the Super Cheap version. Plating is sound and it’s a good fit. The padlock is not bad and a bit more robust than the others in the market.
