I own one and it's one of the best Kickstarters I've supported. It comes with a nicely designed box, a thick user's manual with lots of BASIC program examples in it, in the spirit of the original ZX Spectrum. The design of the keyboard is fantastic, both feels like the old ZX Spectrum+ and modern at the same time. The SD card contains many software, games, apps that you can try out.

ZX Spectrum+ has a special place in my heart because it was the first computer I put my hands on and made me fall in love with programming. This one truly feels like a spiritual successor. I definitely recommend it whoever feels the same way about the old speccys.
