The small one can be used to open lids in jar cans.
These wrenches of both size isn't strong enough. When I try to turn, the strap gets extended. So it never loosen something tight.
I bought this set for loosening the oil filter of mostly european cars. I didn't want to damage or scratche on the cap of oli filter. Because the strap is made of rubber I believed it worked as I thought. But it doesn't.
This concept and idea is really great. It works in the kichen when you open a jar of sauce or something. But this set is not a tool for auto mechanics.
These worked better getting an arc oil filter off the the pen wrench
easy to use and little one works well for stuck lids
On my prior car, the oil filter was in the worst place. Hard to get a pair of slip joints or oil filter wrench in any direction that could give me any semblance of torque or leverage. On a whim I bought these over an old school chain wrench, and wow, worked like a charm. Easy grip, the belts gave very little, no slippage and didn't scrape up my hands. The handles are made of a heavy plastic, so I don't know if you should open up your own oil change place with these, but for the average guy or gal around the house, needing to loosen a thing here or there, this product will do the job with little to no hassle.
this product is very helpful and easy to use!
