"Unfortunately, my experience wasn't great—the so-called 'waterproof' feature didn't hold up after some light rain, and a couple of connectors failed on me. The connectors also felt a bit flimsy for the 16AWG rating. If you need absolute reliability, I'd look elsewhere."

Replacing all the connectors was straightforward—I just removed the inner casing, released the prongs, and matched the wire orientation in the new connector. Once everything clicked into place and I reinstalled the covers, the engine ran perfectly again."

"I found this compatible with R34 coil pack connectors as well as a few other connections around my engine. Works as expected and fits well."

"I needed a 2-wire connector for my mower’s headlight harness, and these worked out perfectly. It took some trial and error with my new ratchet crimper, but once I got the hang of it, everything looked professionally done.

"For the price, these are decent connectors, though I did find that sometimes the pins didn’t line up and would push out when plugging together. The plastic feels like it could get brittle in extreme cold, but since I don’t plan to unplug them often, they’ll work fine for my needs."
