My vet needed his (generously loaned) Alphatrak 2 back for the week-end, because their other Alphatrak didn't seem to be working. I did still bring it home with me to see if I could get anything out of it rather than flying blind during the week-end. First thing I noticed is that when I turn it on it switches to the "stick + droplet" animation without waiting for me to put it in. Normal? Or disfunctional?
