Like the checker - easy to use, prefer liquid reagent rather than powder.

Much better alternative than the salifert or other kits that rely on colors charts. Much more accurate and consistent.

No more guessing the colors
They give you reagents
Love the simpleness once you figure out how to do these
They shove everything into the case and if you don't put everything back just right it won't close correctly
The instructions aren't as clear as they should be, so i just googled and watched the videos on how to do the tests. The terminology of unreacted sample and when you think about it, on some of these tests, it makes you go huh? So watch the videos.
The battery cover is a pain to get off
Overall so glad i bought these.. no more test kits to expire and trying to distinguish different shades of blue!

I have been using the other test kits out there for a while and decided to see if the Hanna checkers were worth it.
I LOVE them and wouldn't go back after trying them. The digital readout is easy to get and accurate.
So much easier, don't hesitate to pick up this product today!

Finally an easy to use easy to read phosphate meter that doesn't cost an arm and a leg. I have tried different brands in the past and all the results were very hard to read. This unit reads it in digital versus me trying to read the colors which are usually very faint. I would recommend this Phosphate meter to anyone looking for a simple to use accurate reading.
Very happy By Aaron on 1/22/2012

Wow, this product is outstanding. No more reading shades of blue. It's accurate down to 0.01.
The only complaint I have is that you have a 3 minute time limit to mix the water and get the bubbles out., just to save the battery. The first time I tried this, I didn't make it in time. Be sure to have your reagent packet open and ready to pour. Also, limit yourself to the recommended 1.5 minutes regardless.
