I will be getting one...as soon as financials are looking better. There are pluses and negatives to it, however Neptune has done a great job over all. All sensors will need to be cleaned. Wireless would be nice, but then you risk a battery in your tank. I would use it to work with my dimmable lighting. It would be great to track the decline of T5 bulbs over time as well. One thing I would like to see is a portable option somehow so that others who may not be able to afford a full apex can still get a read from a friend with one. Limiting this to only Apex users is a slight downfall, but a good business decision.
