Review on COROTC 7 to 4 to 5 Way Trailer Light Adapter, 7 Pin Round to 4 Pin Flat to 5 Pin Flat Blade Trailer RV Boat Connector Plug – Enhanced SEO by Wesley Bell

That thing really does look like a premium product! It's a good weight, overall the case looks like a hard plastic has been used and the pen caps are a softer plastic than I expected and they're quite firm. Went to the truck and plugged it in, the setup was awesome and held in place pretty well. The product didn't move at all (didn't wobble) once seated and it took a fair amount of effort to pull it out. I am not worried about this product shifting when riding on bumpy roads or plug issues. This is a very durable product!
