I purchased a meter from them, Precision X for the low carb diet and checking for ketosis back in March 2017. I'm writing in June 2017 I purchased the strips to with it on Amazon. The test gave me an error. The directions in the manual state that the lot numbers of strips and meter must match, but they didn't and there is never any mention of this except on page 18 of the manual. I didn't use it right away (not smart) and by the time I realized it and pointed this it out, their response was, 'we don't sell that any more'. If they refund my money I will add to this review, but that does not sound like good business practice to me. I have yet to call the maker, Abbott and find out if I can still buy the strips to go with my meter.
