It’s pretty expensive for just a chemical monitor (and only two parameters at that ...). The real test of this system is in its fully functional mode acting as both a monitor AND dosing system (acid and chlorine). It would be interesting to see someone on TFP actually use it as it is intended to see the performance. I know it’s been run through beta test pools but real world, end-user experience (unbiased from affiliation to the parent company) would be most interesting to me.
And the App needs UI/UX work (all apps do) ... they should work with the Pool Math developer and create an API to allow Pool Math and Water Guru to share data ;-)
