[I often do this in the pool and with kids splashing water and waves, and with my aging eyes I'm just happy to hit the opening.] I imagine my numbers would be better if I ensured this uniformity.

Using the cheap OTO chlorine tests I could never figure out which shade of yellow I really had (and was limited to 5ppm TC as well). The ColorQ really has alleviated my concerns in this area providing a very accurate reading on the FC, CC, and TC amounts. The PH readings are virtually spot on with my other drop tests. The ALK tests are in-line with drop tests, maybe a tad on the low side.

I too contacted customer service at LaMotte re: the CH readings. Charlie is excellent to work with and I have never been on hold for an extended period of time. They sent me out a new set of CH reagents (at no charge) but my values stayed the same. [They told me I did not have a problem lot and they must have been correct.] I am running about 70 points low compared to my drop tests. [ColorQ shows 200 and drops show 270.] I can live with this now that I have figured out the adjustment amount. Having a gunnite pool I was concerned I was too low but everything seems to work fine.

I really enjoy how precise the tester is and the ease & quickness of the tests. No more trying to remember was that drop 20 or 21 I just put in. All in all I definitely recommend it.

PS. It also satisfies my mad scientist cravings!
So Mike-which test do you think is accurate (Taylor drops or colorQ). I also get 205ppm from ColorQ and 290ppm from Taylor and was considering adding more CaCl. Leslie gets 350ppm. I thought it may be some pool water interference from some unknown and just maybe colorQ was the accurate one. I have an inground concrete pool (1 yr old). Tech support was great and replaced both my meter and also the CH2 reagent. At that point, I thought the colorQ was the accurate one. Either way, I think colorQ is a great tester and am happy I bought one
