The introductory price is pretty good. I don’t know if I’m in the market for another single encoder device, but I like that there’s no funding risk associated with ordering.

Could be interesting if some developers take advantage of the open source platform and I know some of you really appreciate things like a granular engine in a small footprint.

I was going to pull the trigger on this, but they dont ship to the UK yet.

That sucks considering they’re losing customers if they won’t ship to common destinations! Did you already confirm with them that they can’t take your order directly? It looks like there’s a contact form on the main page of the site. You could at least give it a try, if you still wanted to pre-order for April.

Update: UK shipping added, and I’ve ordered one. The team behind it are really helpful and open to engage on their forum.
