I am extremely frustrated at this point. It is completely insane that the meter worked for 2 months and it gave in. What kind of warranty is that? I will not recommend this meter just because the one year warranty basically means no warranty or worse than without warranty. Without warranty you know you're burned and go buy another one. With this "warranty" you have to wait for a loooong time and you can't buy another one because it is "on its way". If you still want to buy it, make sure you don't mind to wait for a long time for replacement when something goes wrong.
So, the advertised one year warranty is not really one year, and the company does not stand behind its product. They might easily use the same argument if a buyer attempted a return a week after purchase!
If you are a 1st time PH tester user, be aware that you need to keep the tip moist in storage to prevent drying out. I use distilled water in the cap. close the cap with meter upright and stand it up on the cap. It dries out after 2 days, so be sure to top off the water in the cap each day when not using it.
It's very very easy to use and read. Make sure you don't submerge the whole thing, you only want to dip in the tip of it - about half the tip into the water, stir it around a little bit, gently, then wait for the numbers to stop moving. Keep in mind, they may not fully stop and fluctuate between two number (ex: 7 - 7.1). Remember to gently wipe it with a clean, soft cloth when you're done before capping it again.
I also like this came with a little case which I thought was wonderful and handy. Within the case, there's also a tool so you can recalibrate. I'm definitely happy with this purchase, got a great deal (at the time I bought it), and would highly recommend
the ph to insure it is stable that's what I am doin so far so good
//////UPDATE//// VERY UNSTABLE NOT ACCURATE AT ALL I BOUGHT 2 AND ARE JUNK
this stopped working 1st week stays at 6.1 even after calibrateing
buy a brand name tester
