I've always had testo. I'm a service technician and I depend on them a ton. Clear numbers very accurate

I've used other brands and prefer their simplicity much more

Wanted to get this for a wile im so happy I finally ordered them ...

Learning how to use it but it works great and what I’ve learned so far

Water goes inside the gage Easley .

Not enough info about the product !!!!!!!!!the picture is misleading the hoses DO NOT !!! come with it, neither does any batteries like it shows on the package label when I received itif I knew it didn't come with the hoses I probly would have spent some more $ and got one that hade hoses with it even if it was short 3ft hosesthe shipping was not trust worthy all I got was it was shipped and I will receive it with in 30 days didn't get the correct shipping info till about the day before it was going to arrive and I was out of town on vacation and had to run back home so it would not suddenly walk away from the house
