I use Accu-Check Compact Plus. After going off the wagon for a couple of years I'm back to monitoring myself very closely throughout the day to learn my reaction to various foods and exercise. This can get costly! I still had boxes of strips left over from before which were now 1-2 years past their expiration date. Comparing their readings to new strips showed no difference. That said, the nice thing about the strips for this meter is they are stored in a cylinder of 17 strips which keeps them sealed, eliminating issues with moisture and such. Can't say how this applies to individual test strips exposed to the elements. For what these things cost, assuming you aren't keeping them in your hot car glovebox why not use the old ones along with new strips and keep on eye out to see if you get any readings that seem out of whack.
