I recently found out that Freestyle lite strips work with my Alphatrak meter and cost about half the price. My question for anyone using this combination is which number do you input on the meter? Do you use the number off the Freestyle box or stick with the one from Alphatrak strips. My AT strips has 16 and FS are 11 and so far I have been using 11 while I use the FS strips. For a recent check I used both strips and got 310 with the FS and 356 with the AT.
