These are very well made and fairly easy to use. My one critique would be that the screws are very small and fall out if backed out too far when you are inserting wires. Would be nice if there was some sort of retainer that made sure that screws don't fall out when they are all the way open.

Decided to take a gamble with these for my front yard garden. Never tried these before. When I first received the package I thought they didn't include the smaller set of O-rings, but they are already installed on the end caps. Easily just remove them and install the other O-ring size if needed. Really impressed with these. I never knew these things even existed.

Product met all advertised specifications, is well made and easy to install. I used mine to splice a pool valve actuator.

Travel trailers have narrow walls...too narrow for normal splicing. This this and its companion products do the trick.

Great waterproof alternative for outdoor wiring.

It did not come with the yellow O-rings as shown or the large ID rings set.

Good Quality Product
