IdeaFormer PEI Spring Steel Sheet 310x310mm, Double Side Textured PEI Heated Bed with Magnetic Sticker for CR-10/CR-10S,CR-10S pro, CR-10 V2, V3

This is my 2nd favorite bed type, but opted to use this over the favorite.I had the black rubbery magnetic bed plates and the adhesion on that was awesome, but was thicker so I had to se another type of auto bed leveling sensor and was prone to damage by the nozzle more.I struggled with this product AT FIRST. I had to set my temp's 10 deg higher on the bed and then still struggled with adhesion a little. You have to clean the bed with Isopropyl alcohol after every use but the more I use it the better the adhesion gets and sooo glad I stuck with this. Having thinner material means I can use a sensor that needed to get closer to the bed. Removing after printing is much easier to do and the strength of the magnetic adhesion is much better than the black bed material.Cleaning the bed is so much easier also. Once the initial shiny almost oily top surface had dulled a bit it sticks so much better than at first use. I have had a couple of failed prints where corners have lifted and found turning off the nozzle fan gave me better results than leaving it on as it stops the filament from contract quickly from the cold air which stops the filament from lifting.Overall not perfect - hence the 4* rating, but close enough that I would definitely buy again

Seems like a great bed, however despite being advertised as 220x220mm, it actually measures approx. 225x225mm meaning it was ever so slightly too big for my needs.

After applying this surface to my 3d printer and spending some time tweeking the Z offset I havent had any problems with bed adhesion prints stick well when the bed is hot and they fall off when the bed is cold

absolutely the best thing since sliced bread!! Having got fed up of either breaking prints trying to get them off the bed or cutting my hand with the scraper tool I invested in this product. I don't know why i didn't do it sooner!!
