got them to make leveling bed easy to do

I havent had to level my bed since I got them months ago.

These are fantastic. I don’t have to level my bed anymore. On the ender 3 pro the back left is a bit too big. This company is fantastic. They sent me a gift that cost more than my purchase. The gift did not influence this review. They are spacers not much to say other than they work great.

Installed on my Sainsmart Coreception 300 (https://www.amazon.com/dp/B089GMWCS8/ref=cm_sw_em_r_mt_dp_26MUFbSCA4S0Q?_encoding=UTF8&psc=1) I had high hopes for these. But I still have to tram the build plate between every print. I would say stick with the stock springs and save up for a BLtouch or EZABL.

Ive went from the stock springs on my ender 3 to the yellow upgrade springs, to these. If you compress them quite a bit then set your Z stop switch so that when leveled they are about half compressed- then they hold level amazingly well. Been running them for some time and level stays put. I like them.

Great product. But too short for my bed.

Much better than the springs.

Slice and supplement the existing, cut 1/4 from 2nd set . (clear y stepper this way). Solid base for our monster printers. My leveling technique: live Z/baby-step adj. (20 mirror on AMZ a must!!)

Work great

It was good while it lasted. Had it since Aug 2020. It lost it shape a bit.
