Installed in my RV.
This product works well. It is somewhat difficult to mount. The contact points are a little too close together. These deficiencies are understandable given its low cost and small size.

Purchase a very good set or at least the correct cutters for this wire. I’ll make your life hell .
Glad I bought it when I did. Copper has gone way up. And this is full core copper. Place my copper ends on the stuff works great. Using it on a solar battery bank.
