Disappointing Quality of Industrial Springs

Our team ordered compression springs from this brand for use in our industrial and scientific applications, and we were extremely unsatisfied with the overall performance. Using this product, our team found that the springs were not properly stamped, resulting in incorrect pressure and a lack of stability. The product's website promised impeccable quality, but that was clearly not the case, and we will not be returning for any other products.

Pros
  • none
Cons
  • poor quality, lack of stability

The perfect solution!

I needed a set of moderately strong springs for my Tesla Model 3 trunk braces. The trunk now closes more easily and opens fully when opened.

Pros
  • Load Type
Cons
  • Not sure

Ender 3 v2 Z axis limit switch adjustment required

Bought these to upgrade my Ender 3 v2. However, there are more coils and they are thicker, which causes the spring to bottom out on the standard Z-axis limit switch, which resulted in me having to move the limit switch about 3-4mm. Also, I don't feel like they made a huge difference in keeping the bed level. Perhaps the older Ender 3 v1 had a bigger problem.

Pros
  • Material
Cons
  • Long delivery time
