As a happy owner of a HackRF, I can say that this is better than the HackRF in basically every way other than the 5GHz band coverage. They have the advantage of producing their own custom chip, unlike the HackRF. To offer this at the same price point* seems pretty "next-gen" to me.

*Kickstarted HackRF One was $275 with case, Lime is $300 without a case and $500 with so it's still a bit more expensive.
