Review: Works as advertised - Installed on my welder to match the socker i have on the cart. Works great.
Review: Better quality than expected, great value for the price. - I’m using this for a generator hookup and it is ideally perfect for my use. The plastic was thicker then I expected and built quality was good, not as good as the premium one over twice the cost, but great for my need. I’m using a generator producing just under 40 amps, so my cable is using 8 AWG conductors and the cable is a perfect fit, if you were using 50 amps with SOOW 6 AWG 4 conductor cord would be a little too big and I’d recommend spending the extra for the very high quality plugs with the triple finger grips and compression screws on the wire contacts. This plug will also work fine for the range indoor cords with 2 x 6 AWG and 2 x 8 AWG with a thin jacket, just the indoor/outdoor SOOW 6 AWG cord is way too thick and would require grinding out the hole for the cable to a larger size.

### ⭐⭐⭐⭐ Well made but lacking key information
*by K***. on April 27, 2021*

This is a very nice product--I'm very pleased with it. The directions are lacking, however, creating a potential installation/usage problem. The removable 2 piece grommet at the end should be noted in the documentation--how many pieces should you use with what gauge wire? You can't have it too tight (it won't seal) nor too loose (doesn't provide strain relief). A trimming guide would also be useful to cut and bend the heavy gauge wire correctly the first time....6AWG is tough to work with in a tight space.
