the price is reasonable (compared to Sonos)
That combination of words would usually imply that it's cheaper than Sonos (many people think Sonos is too expensive), just so everyone's clear, it isn't cheaper than Sonos it's typically €100+ more expensive than the equivalent Sonos device.
What does look interesting is their combined player/NAS/ripping device, which looks reasonable value, compared to some similar devices.
Their attempts at multi-room grouping don't appear to be as good as Sonos though, less than 5 units and you can only create ONE group of players, according to the FAQ you MAY (note, not CAN) be able to create two different groups of players. How much that would actually limit anyone in practice is a different matter though, I don't know (m)any people with more than 5 Sonos units, so it's probably irrelevant for most people.
