KOYOFEI 5PCS Screen Protector for 10.1'' LCD 3D Printers, Screen Protective Film for ELEGOO Saturn 2, Saturn 8K, Sonic Mighty 8K, Photon M3 Premium Resin 3D Printers

Worked great. Don’t forget to get some of the black tape stuff.

These are easy to install and make mistakes of resin tray leakage a worry of the past! Unfortunately, if you mess up the application you have to start over, but if you follow the instructions it's easy as can be.

Everything about this pack was above expectation! I’d definitely recommend and purchase again. Works better than expected! Great value too!

Seems a tiny bit undersized for a Phrozen Sonic mighty 8k. It's best to install this *before* the tape around the LCD. Kapton tape works great for that purpose.

This item is not the right size for the Anycubic Mono 4K, no matter what the description says. It’s incredibly frustrating to waste time and money on something that clearly wasn’t properly listed. Now I have to deal with the return process just to find a product that actually fits. Extremely disappointed — this should never have been advertised as compatible. Save yourself the trouble and look elsewhere.

You don't need a long review for this.These do the job and they don't break the bank.Works on my Photon Mono 4k, will be ordering again if needed (my machine takes a decent bit of abuse 😂)

Scratched LCD but I put this on top and it has printed perfectly. About 40 items from simple medals, to single file articulated pieces. I wish I had known about these from the start.

Here's the problem: I was under the wrong impression that this would protect my printer from resin leaks. I did not see that the description says "just covers LCD screen." It does NOT say "covers seams of LCD screen," which is what I needed. Because the tape that replacement LCD screens come with to seal those seams has glue that is dissolved by resin (making that tape basically useless...not impressed, Elegoo). I wanted something more robust to protect the electronics, because I've already had one screen fry from leaked resin.Technically, the item description does explain this. The exact size is in the item name, yes. But it's confusing, because I don't know what purpose this is supposed to serve. My Mars 3 has a plate of glass that covers the screen, which can be cleaned with a No. 9 razor blade (which will not scratch glass) if resin cures on it. Making a protector like this--which is exactly the same size as that plane of glass--completely superfluous.They should sell them a quarter inch larger on each edge, so that they actually do something. I should have just bought a size larger or something, and I may, after I stop being angry about how useless this purchase was (and why doesn't Amazon have an "I ordered the wrong one" option for returning things. didn't they use to??).
