FESA 1000V Insulated Offset Box End Wrench Set (8-Piece) - Professional Insulated Wrench Set with Traction Handles, Durable CR-V Steel - 1000 Volt Tools for Electricians (Metric Sizes 7-19mm)

Nice protective covering. Easy to grip. Work well. Needed to do battery maintenance and repair along with installation.

Size is inaccurate, it is bigger than standard matric wrench box, I had used 10mm wranch and i could open the electric box becausd this tool did not give and grip on the bolt head.

Very well made for the price

I looked on Amazon when I ordered these and it was the cheapest set. Suddenly another brand priced theirs cheaper and with a coupon for a limited time. With that said they were the cheapest option on Amazon when I got them. Who knows how long the sale will last on the other. This one also comes with a foam tray for a toolbox which is great. Plus these just look better. I have no way to test these in the sense of what voltage they can handle but I will say that these appear to be very nice and solid and just well made. I plan on doing a solar set up and trying to build a little off grid getaway. These will be great for any maintenance I need to do. The 1000 volts limit is overkill for that but better safe than sorry. I definitely recommend this.

First, these fit very well with a slight amount of space but not too much. So they don't look like they'll round anything over. They have the 'right' amount of offset to fit fingers under it without being so much they torque out. The rubberized coating is nicely sealed and feel sturdy. Additionally, the packaging has a very nice fit foam holder in it made for organizing your tool box drawer, which is made of nice foam! Overall, a good product.
