Review on 🔌 BIRDWISH Waterproof Interlocking Electrical Connections by Rob Parsons

I tried a few others to protect the block heater plug in my 2002 GMC Sierra 2500 HD and they were all too big and bulky. This one was perfect. It may not be entirely "waterproof," but it will do the job very well. Ripped off 1 barrel as there is a small chance water can seep in there without the rubber pads that other styles have. Not a deal breaker as the size is spot on.
