I've never seen this product in action, but it doesn't look like it would do anything for you that daily testing won't do better, more accurately, and much more cheaply.

Since it advertises that it walks you through steps and specific chems to use to correct whatever problem it senses, it would be interesting to see if it takes the pool store "throw all this in the pool and see if it works" method, or the BBB method. Bet it's not BBB..........
