Good product
Worked very well. Tight fit which is great for protecting against water and dirt getting to pins

Bad reviewers don't know how to use this READ
Fits great and works exactly as advertised. If you let this dangle in a downward facing position it will fill with water, hold the water, ruin your plug and prove yourself to be an idiot. You have to use this with a tongue jack bracket or some other apparatus that holds it in an upright position when capped and not in use. If you have sense enough to understand this then disregard the negative reviews. I especially like that this one clips back to the cable while in use rather than flopping around while in transit. Also, the ring that goes over the cord end is stiff! Use a screwdriver or something to help stretch it over the cord end. It will go! I think I saw some reviews that said they had to disassemble the cord end and remove it in order to install the cap. Wrong. You just didn't try hard enough. It won't break. Make sure it isn't extremely cold and stretch that sucker. It will go. Then you have a good fit that won't come off. ... show more

Fits great and clips to the cable nicely while in use
It is a five star value, I did not remove the plug to install the retainer ring. I choose to tie wrap to secure it to the cable. It is the only area for improvement. The material is playable and feels like it will last and it goes on easily and is snug. Buy one it is a good value.

Make sure you position the plug upright to avoid water inclusion
It seems to work okay. However, when I first put it on after cleaning the terminals on my 7-connector harness, I hung the plug downwards (terminals at the bottom) on my trailer A-frame. When I went to use the trailer a few days after a good rain, the cap had significant water intrusion, pooled inside the cap itself, and water additionally in each of the terminals. It seems counter-intuitive, but you should ensure the plug is hung with the terminal end upwards to prevent water intrusion. ... show more

Floods out the connection
Installed this on my new camper. After a heavy rain the cap collected the rain and flooded out the connector. You need to store the cable facing up to prevent it from happening.
