Poor design. With pry bar or chisel and hammer it would be easy to break. If your trailer is worth it, spend a couple hundred and by a heavier lock like AMP. 646633
Works well I like the fact that it`s easy to connect, fits 1-7/8" ball up to 2-5/16" and protects my trailer peace of mind 538504
I like the ease of use, however it doesnt fit snug. Almost looks like a couple of well placed sledge hammer hits would knock it off. Probably need something else. 554522
This is just the anti-theft deterrent device we have been looking for. We have an Excavation business and keep a lot of expensive tools and equipment in a 6x12 trailer. We can sleep at night knowing our trailer will still be there in the morning. This thing is very easy to put on and take off. 539334
Perfect packaging and helps keep my trailer mine. 941002

The entire process was easy... Found what I needed, it was cheaper Came within a few days and was exactly what I ordered. 939322
This one of the trailer locks I have seen. It can not be cut off. 939141
These are easy to use and fit a lot of different type couplers These are my 3rd ones for all my type of trailers. Fast delivery as usual. 935435
It works fine after a year exposed to 4 full seasons. Wouldn't exactly say the build quality is superb, but still acts as somewhat of a deterrent to theft (I use other deterrents in conjunction with this). I will say the paint fades very quickly, so don't expect the bright red color to last more than a few months. 935352
Universal and keeps the valuables safe 935213
Its a good value, however in trailer thief you need more than just this alone. 26 dollars I'm sure there is away around this get a tire boot also. 931256
Easy to use. Highly visible. 923566
This Master Lock Trailer Coupler Lock is tamper proof in my opinion. I purchased to of the lock (1 for my boat trailer and the other for my camp trailer. They are very easy to install. 923072
Great product excellent customer service 921359
Excellent product and customer service. Thank you. 913327
Lock fit with no issues on the 2-5/16" hitch our trailer uses. We have an enclosed double axle trailer used for lawn equipment transport. Seems to be fairly secure once locked in. The coating/dip on the exterior of the lock also is a nice touch. Should keep things fairly rust proof when we keep the trailer outside. 909976
Great lock, easy to use. Came faster than expected! 909400
The product arrived when promised. It was in excellent condition when I received it. It seems to work very well so far. 908962
Very good product that works well when trailer is unattended. 907485
Fit great. I like the red so I can see it in the backup camera if I forgot to take it off. Easy for those prying eyes to see as well. 906849
This is perfect to protect your trailer. Very easy to put on and take off. Makes me happy every time I look in the back yard and see that red dot on the front of my trailer. Now to get the kayaks secured! 902817
Worked as described. Happy with the product. Ordered late Monday, shipped Tuesday, received Thursday. Excellent! 902566
Seems to work well as a theft deterrent, but if someone were to attempt picking the lock they likely wouldn't have much of an issue getting it open. Easy to use, overall great value. 897278
