Seneye Aquarium Monitor

Does anyone have any experience with these?
I had heard about it a while back, before the were available. I see you can purchase them now, but it appears to only monitor pH, NH3 and lighting...
I was under the impression you could monitor most standard reef parameters, including mag, cal, alk, phosphate, etc.
Am I wrong?
Pros/Cons?

Anyone with insight, or a little input on these?
 
I believe rckrzy1 uses it. I think he said he only uses it for the light features because the slide has too much algae growth to be worth it. Maybe he'll chime in.
 
excellent par meter . And I got them in the intro stage for $99 , I gave up on buying the replacement things for it.
