Quality was good. Unfortunately it was too short to use. Would not stay connected to my vehicle due to tension created when the coil was extended.

If you have the round plug on your SUV or Pick up this works much better than the 4 way flat plug which is always a hassle to put on. The coiled wire also facilitates a clean installation with no hanging wires all over the place.

Needed for our boat trailer. Holds tight and won’t come lose and length was perfect to not get too close to the ground.

This adapter is great in that the coiled part can wrap around the receiver to find the correct length to join it to the trailer light harness. The plugs fit nice and and the entire unit is waterproof and made from very durable plastic
