Hi Kim I just wanted to let you know that I like the keto strips and I think they are kind of like being accountable for me. When mine dont turn quite that dark, I can usually figure out what it was that I ate that was bad. I figured out that way that the bbq pork rinds had a trace of brown sugar in them and it was throwing me off. Also, are you testing in the morning or evening? I heard evening was best, I think it is more accurate that way. Hope you have a low carb weekend Take care, Kim
