Works well and Easy to install
This solved the issue I had with dead space in the printer. Relatively easy to install, though the video has a glaring error. It shows having to remove and replace the LCD and glass seperately. The one I got had both pieces pre-assembled together. Trying to follow the video is gonna leave you with broken or scratched glass. A piece of advice, wait until you have tested whether the LCD works. Mine didn't the first time and I had to redo the wiring connection. Worked second time, but I now have several wrinkles in the tape. Whether this will inhibit printing has yet to be determined. If you wait until everything works before you do this last stwep it will reduce any issues.

Fit like a glove with easy install.
It fit like a factory part should and fixed the issue with the printer. My child had no issues swapping out the old screen and replacing it with this new one. Printer works like new again. With the help of a video the installation was very fast and simple. Now to just start printing again.

Great product
It's a process but if you follow the YouTube tutorial you shouldn't have any problems.

Solid product, but delicate.
Goes in easy enough if you have the technical skills, but the screens themselves are a bit delicate. The process of disassembling the printer itself is more complicated than is really nessicary. That said, good product, works perfectly.

LCD screen perfect for Mars 5 Ultra printer
The LCD meets all requirements. You'll need assistance if you don't know how to install it yourself, although it's not complicated; you do need to be careful disconnecting a cable or two. It arrived in perfect condition, installed without a problem, and is printing without issue. 100% original and high-quality product.

Works
Awesome! Took about ten minutes to replace and I was back to printing. I got about 1k hours on the first screen. Hope to get at least 600 out of them. Seems to be the real world average from what I can find.

quite a pain to install. frustrated with warranty.
my screen broke for the first time on this machine. I strained the vat and found nothing. I am 2 months out of warranty, so elegoo had no options to replace it without charge although I believe it was machine issues. I think the firmware is not quite there yet. I believe the same thing happened as when the carriage tries to eject itself from the top of the machine and put too much pressure on the screen and cracked it on one corner. that any printer at this point doesn't come with a pressure sensor to prevent this is wild. The machine was also not designed to have the screen replaced. The entire machine must be taken apart and very small wires plugged/unplugged/etc. I think that Elegoo is a great company, but they are clearly segregating their machines with features that should be standard on all machines: wireless, test print array, pressure sensor, drip mechanism, easy to clean build plate. This is most obvious when you look at the new mars 5 and 5 ultra. the differences are ridiculous and will only serve to greater confuse people and drive them to a brand like anycubic.

Esta versión venía con el cristal templado ya instalado, así que solo hubo qué quitar el lcd dañado, limpiar Para aplicar la adhesivos, y listo. En menos de 15 minutos (y con mucho cuidado) quedo como nuevo
