Shipping, Packaging, and Instructions:I was a bit skeptical about purchasing this pH meter based on some reviews about the calibration process, but in the end I have decided to purchase it to see how it works since I have used few different pH meters in the past I knew how bad meters worked. I normally use pH meter to test out the pool water in my back yard, to check the acidic level in my gardening water and my kids' fish tank. What can I say, guys - Wow, I am so glad I did it since this is a very good product for my needs- especially for the price. The meter arrived within few days in plastic box along with clear instructions and nice guide card.Calibration:Calibration process is easier than Hanna or HM. You just need to do it right and do not be fooled by the comments of others claiming it won't calibrate.Conclusion:This meter is great performance for the right price. It is better than pH strips or drops. It gives a stable and accurate reading all the time in comparison with another much more expensive pH meter. Great purchase!

I like this meter. It is convenient to use and seems to be somewhat accurate. The meter just quit on me. Shows for zeros and will not test anymore. Only 2 months old. Cannot figure out how to get it exchanged or returned. Finally figured out how to get hold of Seller, and they sent out a new meter to me. Liked the meter enough that I bought a new one prior to them sending me out a replacement for the defective one. Very accurate unit.

Best all around I have tried multiple pH reader and none of them come close. I had 3 Gaonly reader comparing to 2 others and all 3 Gaonly reading was the same so returned the others

I decided to ditch my fancy tester rather than replace the probe. Not only is this just as accurate, it stabilizes much faster.

Have to calibrate often and no adjustment can be made so your stuck with mixture of ph'd that needs to be the same.Buts that's my opinion!

The first few measurements were fine, but then it started registering wildly all over the place. The same solution measured twice was coming up with wildly different measurements. The solution I was measuring was very hot. That wouldn't affect pH, but I thought maybe it was too hot for this particular tool.

Pros= It’s easy to use. And operate. Cons= It the worst when you try to calibrate it. I did it the way the directions said. It wouldn’t save the reading and blink twice , then it would read the wrong ph. Tried again and no good.

Very easy to understand and take perfect readings for my 125 gal aquarium. Nice handy meter, much better than trying to match up with PH color chart.
