Good quality
Great value for the money even though i expected the springs to wider and taller but i found some other use than what i ordered them for.

Spring fit perfectly and provides strong spring force needed.
This worked perfectly to fix my WORX WG191 string trimmer that lost the spring for dispensing the string. It is a tight fit the provides lots of force for the string advancement to work properly. Glad to have my string trimmer back up and running and not have to replace the whole machine.

As described
As described. Worked as replacement for my Klein spring assisted rebar tying lineman’s. It does squeak but the price was right.

It's a 2-Pack!
Usually happy to find out something ships in higher quantity than expected, but the ended up not fitting. So since I needed two and the super tiny 2-pack icon wasn't on the image for the size I bought I now have 4 springs that don't fit what I need them for. Them not fitting was a gamble, I needed them to fit over something that is 7/8" and they were just a touch too small. Maybe include inner diameter on the listing? Otherwise, they seem sturdy and I am trying the 1-1/8" to see if that will fit and only ordering qty 1 this time!
