i think @dcurtis wrote a great blog article about it, his end conclusion was that it works if you just need to work with yourself but it breaks down the moment you need to sync up with other people.
I just received my NeuroOn. Unfortunately, polyphasic sleep functionality is not included (future?), nor is the ability to induce lucid dreaming, which was the main reason I participated in the crowdfunding campaign.

Most comfortable dream mask I've tried. Other masks I'd take off in the middle of the night. The sleep analysis is interesting and app is easy to use and get around. I've used it for two days now and so far it seems legit. Battery needs to be charged daily and data export would be nice though.
