First of all I have a really hard time liking anything because I'm a perfectionist and expect everything to be perfect eventually After buying various PH meters in the $6-$20 range I've never been really happy as they all have a tiny little hole on the back for calibrating or just a drop of water in the hole on digital models, meter is ready as long as it works properly. I use my gauge every day at least twice a day so I usually get about a month or so from other gauges that just need constant recalibration or just get worse or a drop of water gets in that little hole. All I know is that I think this is the best pH meter for the price that literally feels solid. The lid has a rubber seal and if you put it in liquid for 3 seconds it will give you a base pH and for up to 9 seconds it will tell you exactly what the pH is. There is a piece of absorbent cloth in the cabin. So if you put the cap back on and there's water at the top, it'll soak it up, and you'll have to put a few drops of the solution on that little foam cloth that keeps your electric petal nice and clean. I would never write a long review of pH meters, but over the past few years I've been so disappointed in buying these cheap ones that I decided I'd at least save a lot of people a lot of trouble if they wanted to use their pH meters anymore than once. a year, like every day or every other day, this thing is reliable, and it automatically turns itself off within a minute to save battery, and they're interchangeable. It's also slightly water repellent so the buttons won't be damaged if a little water gets on them. Well I'm very meticulous and nothing is ever perfect but this is the best I've found in the price range so far.
