I recently switched from the original One Touch Link meter that came with my Minimed pump to the Countour Next meter. I still use my One Touch meter at home, but carry my Contour meter with me throughout the day.
I have found that they are both pretty reliable in terms of results; I have done quite a few simultaneous tests and haven't found significant differences.
Keep in mind that even if your result is sent to you pump, you can override it if you don't think it's accurate for some reason.
I like the size of the Contour meter, as well as the color screen. I actually like the tagging options better in my One Touch meter, but dang is that thing huge!
With the contour meter, you can just plug the meter into your computer and upload to Carelink. If you haven't got Carelink set up already, go ahead and do so. It is invaluable!!
One piece of advice: When I switched to the Contour Next meter, I had a really hard time finding the strips to go with it. Bayer makes two kinds of strips that look almost identical - Contour and Contour Next. Twice I had a pharmacist misread the prescription and give me the original Contour strips by mistake, which will not work in a Contour Next meter. Then, it seemed that all the Next strips were on back order. Took almost a week and many trips to pharmacies to find them. Also, my endo wasn't aware that Bayer had a new line of strips out and that office messed up the prescription once as well.
