You can get a new one for $99... The slides cost under $10 a month. You never have to calibrate it because you replace the slides every month and they come precalibrated. I have an app on my phone where I can check my temp, ph, ammonia levels, and o2, anywhere in the world. I like it. No it is not a controller, but it does give me piece of mind.
