yes I use both and do have faith in the digital. I like the accuracy with the digital as you get down in the five range and lower the colors are real close between 4 and 5 so i feel not as accurate as the digital. The flora nova I use gives the solution a brown tint and it affects the coloring of the test not a lot but yet enough. the digital has been good and yes you are correct it needs more attention but it is very stable. I clean it every use in fresh water before and after test. I store it in 7.0 calibration solution, and I verify its accuracy when ever I feel I need too, have only had to calibrate it once. custom made some containers for solution storage and other little things like that but once done very easy to use and verify.
