Had a frayed, exposed socket on my boat trailer. Swapped in this one—clean, covered, and safe. Now I don’t worry about shorts in the rain. Simple fix, big safety gain.

Housing Feels a Bit Brittle – Handle with Care
Dropped it during install—no cracks, but the plastic seems thin. Probably fine under normal use, but wouldn’t survive heavy impacts. Internals are solid, though.

Good Value for a Simple, Critical Part
It’s just a connector, but when it fails, you’re stranded. This one feels built to last. No corrosion, no intermittent signals. Peace of mind for under $15.

Clean, OEM-Looking Design
Replaced a cracked black plastic unit that looked sloppy. This one has a smooth finish and tight seams. Looks factory-installed. Adds a professional touch to the hitch area.
