Easy to use, accurate. Purchased to extend the length of time between GFO change out. Should pay for itself over time as I was changing GFO on a schedule and it appears I was changing out too often.

This is exactly as advertised. I will not go back to my old way of testing phosphate. My only gripe is the titrant used. It comes in these tiny bags which are difficult to put into the test tube. I would give it 4.5 stars, but I have to round down for this one.

Extremely accurate, no more color guessing. By Brian on 2/2/2015

Well built, and easy to use. I only have a couple caviars; if you follow the instructions the unit will turn off while you are mixing the reagent. I recommend mixing it while using the second included vial to zero the checker. It only comes with 6 reagent packs, so be sure to order more. Also when opening the battery door, be careful to pry it straight away, do not pry it off at an angle, you will bend the connected pieces.

I really love the idea of this test meter, but the execution needs a little help. For the most part, it's great. Love the design. Easy to use. No guessing at colors, unlike other test kits. The only real issues that I have with this tester are the limited number of reagent packets provided with a new test kit, and the reagent mixing time. The instructions tell you to shake the vial for 2 minutes after adding the reagent. The problem is that the meter shuts off after two minutes. Another sixty seconds and a few more reagent packets, and this would be a five star product.

I like this test kit. For less than $50, I find it to be a bargain. Its easy to use and doesn't take long (about 5 minutes total). It's an important tester to have if you have a reef tank.

This is a very simple and accurate test for phosphate.
The one thing I will say though is that you need to use both test vials at the same time. The instructions talk about going through the test , then adding the powder, then shaking it up, then putting the vial back in. The shaking/mixing takes 2 minutes and the checker turns itself off during that time... So I fill both at the same time, add the powder to one, shake it up, then run through the test.
Works perfectly this way with very accurate results.
A "need to have" item. By Darren on 12/15/2014

It's extremely hard to gauge phosphates with other tests because you're trying to pinpoint color differences with the naked eye. This gadget does all the hard work for you in minutes!!! Amen
Way better than matching colors! By Josh on 12/12/2014

This meter is great. It takes a bit of practice to get all of the reagent into the sample but it's much better than training to match to colors by eye.

I bought this cause I used other test in the past and can't get a good reading. 0.0 - .25 how can u tell exactly what your levels are at. I'll tell u Hanna checkers. Gives u a digital readout I love that. I have the phosphate and alkalinity tester. Works great. The only down fall is buying the test solution. It's a pain to have to order it and for 10$ for 25 kits it's not the cheapest test kit. But I wouldn't use a different test again.
