This is a serious, high quality wrench. It works perfectly for my 2 gallon Jerry Jugs of chlorine. The seller even hooked me up with a custom orange-colored one. I sent them pictures with measurements and they double-checked it would fit...and yes, it fits perfectly! This is so much nicer and easier to use and store than when I used my oil filter pliers! I can't express just how professional, caring, well-packed, and caring this seller is. This was an excellent experience!
