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.

Perfect replacement
This kit includes everything you need to replace a defective screen. You will want to follow a tutorial online to make sure you have everything connected correctly, but I was able to do it on my own with that kind of help. Works great!

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.

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.

Review is for the customer service
This review addresses only the customer service. The replacement screen was faulty. Customer service sent a free replacement damaged in shipping and then another replacement. That one also didn't fix the issues. After more debugging, Elegoo arranged a replacement of the whole printer (it was 6 mo old). That was failed catastrophically on the test print (causing damage to the printer and table). At the end, Elegoo refunded the printer and replacement screen, sent several bottles of resin as compensation, and informed me how that the printer failure was used to improve the design of furure versions to avoid the issue. As far as customer service for the company, they were very polite and responsive the entire process and kept working to resolve the issue.

Replaced the screen and it stopped working straight away, not sure what the issue is. Contacted elegoo support and they said they would ship another unit, annoying that it didn't work in the first place but hopefully the next one is fine and they didn't require additional shipping or anything which is convenient

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
