I have to order more product for my test kit so I was wondering what the benefit of this item would be. I mean, I only have one pool. It looks like it only fits the round test vials so it would not work for Ph, which I am testing as often as chlorine these days.
Does it help for anything more than just stirring.. does it make the test more accurate? or is it really just great for people who do water testing for a living?
Thx for your opinions.
