Fast shipping because of being a choice item. Price is fair. Second time purchasing. I bought again as all parameters seem to test fairly accurately except nitrates. Even after 2 werks between water changes it’s shows zero. I find that almost impossible so i will see if this batch is the same. Other brands show a reading for nitrates but are not as accurate with ph etc. At the end of the day these test strips in general are not the best way to test water and you should use the proper meters. Overall these are the best bang for your buck.

I have tried one and compared it with the Será strips, and the results are the same, so they are perfectly compliant, recommended purchase.

Perfect! It works well and fast. And it’s a lot cheaper than other testing kits.

I tested it against a 5 in 1 test kit from tetra ($14 at walmart for 25) and it gave a clearer reading for ph, nitrates, and nitrites than the tetra brand. I’ll be buying these and recommending them to the local fish breeders.
