Super easy to install. The touch screen appeared great. The quality and price was was in the range of what I was looking for. So far the performance has been spot on. Great upgrade for my printer.

Great display! I am using it with the SKR Mini E3 and have it installed on a frankenstein printer that was at one time a Maker Select v2. I am using the stock firmware that came on it paired with Marlin on my SKR mini. Takes some time getting used to the menu layout but not too bad after a while. Nice that it has Marlin or the new GUI menus. I printed a housing for it off of thingiverse.The touch screen works well, as other reviews said don’t over tighten the screws you are mounting it with. Seems to be well made, I haven’t had any issues out of the hardware.

Every BTT Item I Have Purchased Is A Failure. Two SKR Mini E3 V3 Control Boards. Junk One Filament Runout Sensor. And A TFT35 Mini E3 V3.0.1. I Sent Two Items That Were Ordered Together A Control Board And A TFT Touch Screen Back In The Same Package That I Received The Two Items In. I Have Only Received A Refund On The Control Board. I Have Yet To Receive The Credit For The TFT Touch Screen. I'm Waiting For My 42.21 Dollar Credit. All Items Were Returned And All Return Shipping Labels Were Included In The Original Packaging. I Ordered Creality Mainboard And LCD For My Upgrades And Both Items Worked Without A Hitch.

Great Replacement, much handier than the original. Plenty of videos and tutorials available on YouTube to walk through the process of replacing.

I bought one of these for my CR-10 mini. I spent about two days struggling with getting serial ports configured properly, but eventually, I got it working.I absolutely love having a touchscreen GUI to control my printer with, even when the GUI is controlled by an external microcontroller and that sometimes causes issues configuring.If you want to go back to the old way, you can switch to "Marlin Mode". If you're using Klipper, the touchscreen GUI won't work (AFAIK) but marlin mode will, so long as you get the display configured properly.If you're not afraid of a little bit of troubleshooting, this is a great screen to control your printer with. It has its own USB & SD card port for g code file importation, but if you're using something like Octoprint, Mainsail or Fluidd, that doesn't matter so much.For anybody struggling to get the touchscreen GUI communicating, set one serial port to -1 (for usb control) and the next serial port to 2. Set baud rate at 115200 to begin with, then make sure the TFT is listening at 115200.Lastly, make sure your TFT wires aren't plugged in backwards. It won't hurt anything to swap em around.

I am just getting around to hooking this screen to my 3D printer build and it does not work, it doesn't recognize the printer and I've spent hours troubleshooting. I cannot get any assistance from Bigtreetech and now I'm told that I can't return the item. Will never buy again.
