Here we can discuss about the problem found
I've got 2 LILYGO E-Paper screens on order but it was one of those offers which "if it sounds too good to be true . . . .". 2 screens (without touch) for 20 quid! It did look like a reputable seller; lots of other items and they're still trading, but at that price I feel I may be testing AliExpress' refunds procedure soon. Still within the delivery window, but time will tell.
