I've been using one of these for a little over a year and I am pretty satisfied with it. However, it is a little tricky to use. For one thing you have to be careful in drawing the sample to avoid contamination from skin creams, lotions, etc. In addition, some people have a problem sticking themselves with a lancet or other sharp object to draw blood and the application of the blood to the test strip requires a steady hand.
That being said, my results have been generally consistent from test to test (I test monthly), with only an occasional fluctuation in the results. I had the opportunity to have blood drawn for a lab test within 45 minutes of testing with the machine. The Total Cholesterol and HDL tests had a less than 10% difference. However, the Triglycerides results varied by a much larger amount. I'm not sure why this happened.
The only real complaint I have is the cost of the test strips. Still, they are much cheaper than a lab test and are an easy way to track your cholesterol between visits to your doctor.
