Good stuff.

Well made, inexpensive
This was well made and strong. It is a Curt, so if I need to replace the latch some day I can. The only issue I had was a misalignment between one set of the mounting holes and the holes in my trailer tongue. In all fairness the misalignment of the holes could be because of my trailer, not necessarily the hitch. No problem, put in the first bolts then used the hitch holes as guides to drill new holes in the tongue.

This is a 1 7/8” Hitch
Excellence Quality, but buyer beware! This is a 1 7/8” hitch, read the product description carefully, I was too hasty and a bought this when I was really looking for a 2 inch model... Now it’s too late and I can’t return it. Learn from my stupidity (In concert with Amazon’s less than optimal description)

Worked well easy to install
Bought as a replacement for broken coupler on trailer. Was able to sinstall in about 15 minutes. Smooth easy operation. Have had on trailer for a couple of years now and works perfectly.
