Accurate
The meter is easy to use and accurate. The only difficulty is getting all of the reagent paper pouch and into the vial. it took me a couple tries to get it right. Also getting the battery cover off to install the battery is a little difficult. I had to carefully pry off the cover with a knife. I am using it to monitor the phosphate levels in my Aquarium. I would also like to have a potassium meter but they don't sell a potassium version.

Still one of the best options out
A little difficult getting consistent readings with the powered reagent. This product would be a grand slam if it had a liquid reagent instead. Still one of the best options out.

Works great, to a point
This one does from 2.50 down to 0.20Not what I was trying to get but did what I needed. Probably need this and the ultra low together to really lock down your numbers. This one does phosphates so no conversion chart needed from phosphorus.Follow up edit,It's been a few months and this one does go low enough. Great product, would by again!

Unreturnable Item
DO NOT BUY - seller lies to amazon about products containing flammable gases so you cannot reutrn his items even if they do not work

waste of money and false results
They do not work well at all, waste of money. I tested them with 3 different testers. The 3 I compared them to all showed the same results where this was off by 3 + ppms. If using for saltwater this is huge and can really screw your tank. I wish I never bought.

Not really accurate
I was really exited to get it but half a time showing 0.00 phosphates. Which is not right. I have visible alges so can't be zero. Follow all steps as recommended but I think it's waste of money. Very disappointed.Salifert that I used for 10 years way better value for money. IMO
