Awesome, Easy and Accurate...Consistent By JPB on 2/14/14JPB would recommend this product to a friendEasy to use and very consistent results. For the first few months I double checked occasionally with a Salifert titration test...results very similar. Titration can be challenging to determine exact endpoint, especially if you rush it...not at issue with this test. :)

Good product By John on 2/1/14John would recommend this product to a friendI am new to the hobby and found this checker very easy to use. None of my criticisms of the phosphate checker apply here - no problems with timeouts or reagent packets. The results are easy to read.

Good product By Clifton on 1/14/14Clifton would recommend this product to a friendI like the digital read out but still quite a few steps involved, wish it was a bit easier.
Fantastic! Never going back By David on 1/14/14David would recommend this product to a friendPros: Results are fast and easy with less mess than other tests. Only having to add reagent once to get a result is nice. Seems to be accurate as far as I can tell.
Cons: Printed instructions are difficult to read - need to be printed more legibly. (Test process is very simple though.) Display is hard to read in low light. Size and shape of the device could be better for easier handling. Would get 5 stars with those simple improvements.
Accurate But Expensive By Scott on 1/9/14Scott would recommend this product to a friendI really like my Hanna checker and found it to be very accurate when compared to Red Sea and Salifert. My only gripe is that the reagent is expensive.
