I have backed this product for several reasons. Primarily, it will give me a little more free time from water testing in the evening. One of the big hangups for people seems to be the cost of the device. I still don't understand why people (myself included) are so willing to go and spend hundreds of dollars on LED lights, the latest pumps (gyre for example), etc without so much of a question of whether or not they are getting a product that will benefit their reefs over what they currently have. This device can offer a peace of mind that I for one think is worth every penny and give us immediate insight to the health of our reefs. For me, the ability to nearly instantly monitor even just a few key tank parameters without taking the time to do drip tests or question my color detection ability is worth the cost alone. I too have concerns about "what if they don't make it?" I counter that with the simple thought, that if I don't try to support them, they may never make it, which means it may take a very long time before a product similar to this will be brought to market. The simple thought of looking at color reactions forever just pains me.
