Feels solid, pretty heavy. Locks as intended, no problems. I sprayed the keyhole right away with anti rust lubricant, just in case. My advice is to order if sold by Amazon, I ordered from a third party seller (RNR Camper), the lock packaging (not Amazon box) was all torn up, even the previous customer info was still inside

I have a lightweight tow dolly for pulling a slingshot. Once we get to destination, car and tow dolly stay in parking lot. Dolly is not very heavy, and I wanted to secure the tongue from nefarious actors. This fits the coupler very tightly, and combined with a chain thru the wheels to prevent dragging, my dolly should be secure. Unit appears strong. And I like the circular style keyway. Came quickly at a great price. Happy camper so far.
