Works correctly half the time. Otherwise it doesnt. The print can be completly over and it’ll tell me there is 10 minuites left. A print could be half way done and the screen will tell me the printer is idle. Other times, I get ‘data transmission errors’ randomly. Unplugging it (twice) usually fixes it but it’s such a simple device, how could it possibly be this buggy?

It's a nifty little screen, displays a few operating conditions the printer is experiencing. A few...not nearly as many conditions as the phone app shows. Since it's simply a display, and not a control panel, you have to use the phone app anyways, rendering this kinda pointless. Other than it looks cool. And you'd think for the price they could supply a case / mount for it, not make you print your own. If you have a spare $50 laying around and are aching for some way to add a little customization to your printer, go for it. If you want something functional, skip it, get yourself some really interesting color combination filament with the money instead.

It is a cute and fun little device. My largest complaint with it comes in the lack of a back cover. Other than that, it's pretty cool.

Dimensions drawing should be supplied so a mounting can be designed.

Just what I needed
