I am happy with it so far and have had it for a little over two weeks. I use it to test cosmetic products like solid shampoo bars to check the pH. It's easy to use and clean, and when cleaned properly, it remains at 0000, as it should when not in a solution. (I have had to return other brands because, after use, no matter what, they would never return to 0000 and would chaotically read pH values, even when not inserted into anything.) It was easy to calibrate with the solutions it came with (just make sure the temperature is correct when calibrating because temperature is important), and so far, it consistently gives accurate values. The instruction sheet it came with was excellent, simple and easy to follow. This came with the storage solution you need; the protective cap that screws on can't dry out, otherwise, this will damage the electrode spear. You'll see the protective sponge at the bottom where the head of the spear rests, and it must be a little moist with that storage solution to maintain and protect the electrode. I am very happy with this one so far, and it works well, unlike some other ones I have bought here on Amazon. For its price its good and I recommend it if Apera is out of your price range.

Works great!! Lightweight, easy to use and easy to clean!

Good product works well for any sauce

Just what I needed to test meat for fermentation such as Salami! Instantly reads and seems to be pretty accurate as I tested with a similar device for water testing.

works as described. I don't have a second reference meter to confirm the readings but I'm getting the values I would expect from the local water as well as more acidic liquids
