Review on 🔌 BTF-LIGHTING 2 Pin IP65 Male Female Connector 22AWG 7.87in/20cm Extension Cable for Car, Truck, Boat - Small Size Nut Design - Indoor/Outdoor LED Strip Lights/String by Austin Olson

The good news is they are well made and I believe they will be waterproof. Now I test them in frosty winter weather). I have small 4 pin ones. What I don't like are the design flaws: 1) The key that aligns the rotation is very hard to see and doesn't protrude far beyond the pins so you can't just turn the connector until the key clicks. If you do this, you will bend the pin. 2) The o-ring, which should be grabbed (but not grabbed), will fall off if you're not careful and then not waterproof. At least it's orange and pretty easy to find in the dirt. 3) less serious is that the screw on the plug cover between plug and socket is also not caught. Once you solder the wire to the connector you won't lose it. After 5 weeks of use I increased my rating. All of my aforementioned shortcomings remained, but these guys survived 5 weeks in 70mph winds and sub-zero temperatures with sleet and sleet. I have 80 connections and none of them are messed up. Meanwhile, bad weather caused the outer 4-wire safety wire to lose its insulation. I would say it's a good buy and worth the small imperfections. To align them, I just mark them with a metal marker the first time I put them together.
