## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    10 AWG is good for 30 Amps.
  

*by B***O on Reviewed in the United States on July 11, 2018*

For anyone who is capable of wiring a stove plug. It's that simple.

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Seems high quality.  Heavy duty pin sockets
  

*by A***X on Reviewed in the United States on May 18, 2021*

Overall seems extremely heavy duty.  Only 4 stars because no instructions were included.  I can't really tell if the pins are supposed to be crimped or soldered.  I attempted to crimp the ground pin, the 8 gauge crimp worked well, but wasn't tight enough for the 8 gauge wire I had.  The 10 gauge crimp was tight enough to hold the wire securely, but the pin "squished" on the edges.Removing the O rings, and soldering with a torch (like they're solder cups) seems like the way to go... however the holes on the smaller pins allow solder to run out resulting in the need for cleanup.  I feel like these pins are supposed to be crimped, but with no documentation it's too much trial and error.All of these questions would have been clearer if instructions were provided. Since you don't get extra pins you get "one shot" at binding them to the cable.

### ⭐ 1.0 out of 5 stars







  
  
    Only is half the charger
  

*by N***E on Reviewed in the United States on March 4, 2019*

Needed a adapter for a Tesla.... this is only one half the part. you need the other half for it to work. Was not at all clear on the site.
