Review: Good quality - They came quick and great quality! They function as should at a great price. Perfect fir for my aluminum trailers
Review: cheap and functional! - these are great- the springs seem plenty strong, the pin width has plenty of room for all of my trailer coupler latches, the leash is a good length, and they work like they should. I just opened the package, grabbed a cordless drill, and installed four of them on various trailers in minutes. (tip: if you want the leashes to last a few decades longer- add a dab of polyurethane or silicone or whatever to the cut ends of the cables... that's the only place where water will get in and seep and eventually rust the coated cables from the inside. see last photo.)
