We get it, not evvveryone loves a good tease. However, I feel that we did release a good bit of information...like it can test TWO aquariums. Gotta hold some features close to the chest.
However, I did read your message and still cannot confirm price or release. As David said, we are putting this one through the paces...and while I WILL NOT confirm price, 2k is a wild guess.
Hopefully this direct response instilled a big more confidence and turned you back on! Give us a call w/ any questions, we love to answer and engage with users...we are always listening.
As for what you want to do with HYDROS....it's totally up to you. If you want to only start with MAVEN, you can as its a standalone device with SENSE and DRIVE PORTS. However, most Maven users will have this apart of their ever HYDROS Collective, where you may link up as many Controls as needed to do all the jobs you wish.
That the glory of HYDROS for those looking into the system. You can start small and not have to worry about starting over, just expand, and expand, to get the ports needed!
