they have issues to get hold of the CHIP mini pc because they are so popular.
I received my order from the end of December in January and everything is working fine.
A month ago my SDR dongle broke, after a short post here in the forum they send a new one to me.
After only 9 days i got a whole new SDR dognle for free as a replacement.
You should get your device as soon as they have eneugh CHIP pcs.
