We have 2 craftys and no issues at all. We have our "wishes" of what it could do better which are addressed with her big sister Mighty. That being said, for what this little device can do we give both craftys two thumbs up. Unfortunatly I couldnt vote twice on Crafty working.
As for early adopters, I see no need for anything free or discounted. I have been using technology for a long time and understand the risks. Most of my experience has been positive and crafty is no different than the other technologies I jumped in on early.
