22pcs Extension Springs Assortment Kit, Length 5cm 6cm 7cm 8cm 9cm 10cm 11cm 12cm, Wire Diameter 1.2mm, Outside Diameter 12mm, Mechanical Strong Extension Springs with Hook for DIY Repair Replacement

I was looking for one particular size and ended up purchasing a box with a variety of sizes that i will probably never use. The price was right and it did help me finish a project that I was working on.

A good product with a nice selection of sizes. Have used several in an outdoor project and they’ve held up well for over 6 months now.

It work great on my old coke machines.

Too many springs.

I only needed one good spring but it was actually more affordable to buy this whole box of assorted sizes.They are excellent quality and the shipping and packaging is also excellent. Very happy.

I'm not sure if I should describe these as strong or tight. It took some effort to stretch these, so I ended up using longer springs where I would have typically used shorter ones. So basically these were higher quality than I was expecting, so I had to adjust on the fly.

good product

These springs are WAY too stiff/strong for my need (3D printing). They need to list the spring tension of these springs so visitors can make informed decision. Unfortunately I'll be returning these.
