It looks like they are a Russian company - this (sits in the palm of your hand, its so small) model is Digital modes only and only a single frequency on a single band
but at $80 very cheap for a transciever! But it appears to need a 14.2v external supply. ??? (It also needs a computer or tablet to feed and decode the audio of course). They mention it will do FT-8 as well.- it’s purely the RF<>Audio interface in fact.
