Used this a couple of times last year and was pretty happy with it. The supposed AI is a bit of a reach, it simply asks and reasks a number of questions to list you symptoms. On the uses last year the providers, once you get to them, asked a fair number of questions, communicated well and seemed to listen to my complaints of a sinus infection (life long surfer of sinus infections, so I know what they are and what works to eliminate them.) They sent in prescriptions that were appropriate and helped. HAve used it twice this year, once for my teenaged daughter and once for me. In both cases the provider asked few questions and completely ignored the symptoms and personal experience of the patients. For mine, this last weekend, he prescribed otc medications that I had already been taking, that were not helping and ignored that things were not getting better. Denied my specific request for medication that historically helped me and is typically prescribe for sinus infections. The OTC stuff is still not helping and symptoms are continuing to worsen. So I wasted the 30 bucks and the time that my condition could have been improving over the weekend. Now will still have to take time off work to go see a traditional provider. Won't be using K Health again.
