I have the OEM one (not sure if it's Nissan or they just rebrand) but I've had a Curt on my other vehicle since 2010 and aside from a faded decal it still works/looks as good as new (and I used it at least 3 times a week for over 3 years straight)
OEM hitch paint is garbage and it rusts as soon as you look at it funny. However, it is the only one on the market that includes the 7-pin plug socket bracket.
