## Customer Reviews

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Works well for Creality CR-10s (S4 and S5)
  

*by R***Y on Reviewed in the United States on January 27, 2019*

The springs are the size they advertise, but I didn't realize my original springs were 24mm long.  To those with a CR-10s (S-4 and S-5), you will need to buy fender washers to make up the difference, by placing them under the spring.  I used 4 on each corner, and 2 on the corner with the plastic bracket for the heater power cord connector.As for performance, I noticed the bed and carriage wobble have been dramatically reduced, allowing me to increase my print times from 5 to 15% faster on various models and filament types.  It also dampened vibrations to the frame, and table greatly as well.If your aluminum bed plate is 3.5mm or thicker, it should be fine.  To test some of the spring's attributes (while my tests weren't conventional or scientific) I was able to compress the spring down to 14mm in length, with 15 pounds and 2.8 oz of pressure (6.8 kg or 66.7 N of force)I would not recommend these springs for heated beds that are under 220mm in size, since smaller beds tend to use thinner aluminum plates that can stress under the pressure and heat.I hope this was helpful.

    Good quality and strong...
  

*by J***. on Reviewed in the United States on June 1, 2018*

I needed to make an adjustable base for a 
  
Pillow Block Bearing







  
  
     so I can adjust the height at will as I am testing different motors that vary in height. I was skeptical at first because these are advertised as "Heated Bed Compression Springs" but these springs were the closest thing I can find that would work for my needs. Turns out they work great for what I needed. These springs are of good quality and take a plenty of force to fully compress them. Using the index and thumb, I can compress them for about 5mm.They are 20mm long and will work with M5 screws. If you need springs and the dimensions is right for you, I highly recommend them.

### ⭐⭐⭐ 3.0 out of 5 stars







  
  
    Not great for bed compression
  

*by E***. on Reviewed in the United States on January 1, 2021*

These springs are stiff, and I couldn't get them to work as intended for my bed. Ended up using one for my extruder (which works way better now) though I had to cut two coils off to make it work. If you need extremely stiff springs with little give, then these may work for you.
