YETOR Waterproof Connector 4 Wire,16AWG Male Female Plug LED Connector Witch 4Pin Waterproof Connectors IP68 with 20CM Extension Cable for Indoor/Outdoor LED Strip Lights.(5Pairs)

They’re great

These are great for your exterior electrical connections. Length provides lots of wire to work with. Heavy duty cable and connectors are waterproof but not bulky. Multi-pack is a great value. Highly recommend.

I read some of the negative reviews, most seemed to be lacking in the understanding of a pliable material and why it's made that way. I had no issues with the 4pin version, it served as power in and power out for limit switch control. The 16awg wiring was appropriate for the amps and voltage required. All the needed information was provided by the vendor. The only concern I had was the line up marks are hard to read, (being marked in black). White dots would have been a big plus.

Of the 10 pieces received, 4 of them were deformed. This is easier to see in the two on the left due to the angle of the photo. Luckily we only need 2 sets, but you might want to factor in some "throw aways" if you need multiple non-deformed sets. Hopefully, this issue can be fixed with better packaging and the issue isn't on the manufacturing side.

When the connectors first arrived the female connectors were slightly deformed and took some patience to get them opened back up and seated fully. Once they got connected they held their shape better and sealed as expected. When it comes to splicing in the connectors, the ends of the wires are tinned which is very convenient. However, if you are opting to butt connect these rather than solder there is very little wire exposed and connecting all four is a little tight.
