Solid built, worth the money
Extremely stout. Worth the money. I use it to take filters off Cummins X15 semi truck engine. You can tell this will last for a very long time.

Too Big
I got this thinking it will fit my oil filter to my Chevy truck, but this is way too big. I started to send it back but I kept it. Now this is very well made, itâs very heavy duty for an oil filter to a bigger truck or you can use it for plumbing. Itâs way worth the money. It do have some weight to it. You can use it, this thing has versatility you can go right or left with a flip over whatever you trying to loosen or tighten. I think the smaller one fit me most. It looks like it will hold on to the object, donât think it will slide on ya. I havenât found a use for it yet. My truck need something thatâs really thin to get to my oil filter because of the cavity it sits in.

Work great, not too strong for extra tight filters.
Work well for installing and removing filters. If your filter is extremely tight ,recommend using something else to break it loose.

I have used the fabric filter wrenches and have torn lots of them and you always wonder when it is going to give when you have that super tight filter. This filter band grips solid and you never get the feeling it is going to give out. Excellent product. Well made.

That’s the right size for the fuel and oil filter on the ISX 15. By the way, I received it faster than supposed. Two days ahead actually. I recommend GW tool for those who needs good tools for their garage.
