Official Creality PEI Sheet 235x235mm Flexible Removable Spring Steel Plate Magnetic Sticker Heated Bed Kit Replacement Accessory for Ender 3 S1/Ender 3/Ender 3 V2/Ender 3 Pro/Ender 5 Hot Bed Surface

I bought this product nearly two years ago after having constant adhesion issues with my glass bed. It was starting to get bubbling on the bed and decided to buy a replacement as a precaution. Still using the old one for now though but I'll be switching out if I feel like I need to.I have used a lot of different types of printer beds. This smooth PEI sheet is by far my favorite. It's not even close. Love the completely smooth bottom layer. Sticks perfectly when printing PLA and releases super easily.Can't recommend this enough

This bed is nearly as smooth as glass, but with far superior bed adhesion

Ender 3 pro, perfectly compatible

I'm using this on my ender 3 pro and I love it. I had struggled with adhesion on just about every other bed surface. On glass beds I had trouble getting the print to come off. On the flexible magnetic beds I couldn't get it to stick in all places. I also tried a PEI covered glass bed and I couldn't get anything to stick to it. This spring steel is literally the best of every type. It's smooth like glass so your first layer is super smooth. Everything adheres without issue. When it's time to remove the print just a light bend and it pops right off. It's also magnetic so you don't need clamps to hold it on. I will only use this bed from now on. I can't recommend it enough.

Amazing adhesion, removes easy and bends a pretty great amount. Significantly better than the bed the printer came with.

I’m getting much better first layer results on an Ender 3 Pro with BLTouch.

Been printing all month, pla exclusively.Can't say much for other filaments yet but it's been a great experience. While hot it sticks as it should but once cool the prints pop right off.Magnet could be a bit weaker but maybe that'll happen with time. Though it hasn't caused any leveling issues from the force of pulling it off or adjusting.

I was using glass and had so many problems getting prints to stick. It would take 2 to 3 prints to get a good one. Once I got this, no more problems so now I can focus on other parameters.
