Just added the Pinitech UNO displays to my Stern Stars and my Bally (custom) Black Pyramid. I've ordered these before for other machines and have never had any problems. I think that it is cool that you can adjust the brightness. I turned them all the way up for Stars which has frosted 2smd LEDs from Comet. The extra brightness helps them to fit in better. On Black Pyramid, I turned them down a bit to have the muted fire vibe to match the backglass.
I'm sure the assembled ones are great, but I prefer the kit because my 14 year old son loves putting them together. It's fun to be able to provide him projects that will occupy a few minutes of his time. Just like Legos, I turn my back and expect him to be working for awhile, but they are completed and working perfectly before I know it.
Here are some pics of how they look.
