Good: Bright, daytime-readable display. Works as advertised once you get the software figured out (see below.) Very good price for what you get.Bad: Some text effects are rather slow. The device includes its own wifi access point, which is great except that your computer has to drop its wifi internet connection to connect to it, a moderate inconvenience. Appears to be no security at all on the wifi link nor any way to disable it after the display is programmed, enabling some opportunity for mischief. The board really should connect to its owner's wifi router and work through that, or include a hardware switch to disable wifi when it isn't being programmed.Ugly: The software is a royal pain to set up. Took me a couple hours of googling and experimenting to get it working properly. Once there, however, programming the display is reasonably easy, and the built-in wifi saves a lot of back-and-forth with a flash drive.Bottom line: A good, inexpensive display board with a lot of bang for the buck. Five stars, although the funky software almost cost it that fifth.
