This is super old news, but I'm happy to see these get more attention. These released last October.
These devices are delight. It makes a great gift for a casual retro game enthusiast - particularly if gifted with an Evercade cartridge matched to their interests.
Both built-in game line-ups are fantastic, and the Evercade library is a delight.
The big caviat of the whole Evercade set is that the cartridges are really just SD cards inside. So they're not probably going to last terribly well.
