Review on 💧 Water Resistant Fastening Retaining Extension - Optimal for Safety by Andy Tran

It's basically just a water repellent, not waterproof. That's probably why it says it's waterproof. To hook up my outdoor Christmas lights in rainy Seattle, everything works fine. Not a very good seal on two parts of the body, especially on the inside. I've found water in one before, but the fact that it's not actually sealed means the water will hopefully escape before it touches any electrical components. I could probably make something with a similar effect and cheaper, but they're here, so I'm using them.
