So I've switched to the wavesense jazz metter because the strips were cheeper(the cannot reorder until date hasn't changed which I thought was the idea) after stuff I read and heard from other people. Apparently it's not as accurate as some reading the report in back of think like a parcus book and I heard some stuff from other peopl(peepherps there better then were a few years ago.(maybe I'm over thinking and just need to trust it I think the only way that would complete price of mind was if it was tested against a machine in hostpal well I was at an appointment but that's probably a bit excusive) there is one set of test strips I would like to use(because it seems there known to be most accurate and have the lowest operating temperature which would suit my job more but would never be able to get those strips proscribed)
