Got mine and used it for the first time last weekend. ALL of my test results were unchanged.
CUTiger: Can you spell out how you did the FC test before you got the SpeedStir? For example, what I did was:
1. put pool water in vial
2. put in one drop of reagent
3. swirl by rotating wrist three times left then three times right
4. add next drop
5. repeat until clear
With the SpeedStir my FC is a full ppm lower than my manual method. A friend, who swirled slightly differently manually, also went down a ppm and actually she says it is a 1.5 reduction (although I don't know how she figured the .5).
Since you had found a manual way of mixing that is as accurate as the SpeedStir, just wondered if you'd share.
