Losi 4-Way Wrench,Steel (17mm, 10mm, 8mm, 1/4") (AFT)
Really bad build quality, the finish is just not something I expected from Losi. I bought this because I wanted to use the 8mm side and it stripped out from the first time and stripped out the nut I was trying to unscrew as well. The 17mm side is OKAY I guess but I would still be careful with a tight nut. I personally just threw the whole thing out.
