I saw Banggood has Nextion displays with a kinda good price.
But are they real Nextion displays with HMI?
I also search them on ebay, but lot of reviews say they aren't real and work "TJC", which makes them impossible to use with original nextion editor, only with a chinese copy of it.
Don't know, ask them. I am reminded that "if something seems too good to be true it probably is". You could buy one and see, then tell the rest of us what you found.
