Note that the COnfirm and Micro both use the same strips. There is also a ReliOn PRIME, but it uses a different strip -- the strips are cheaper than the Confirm/Micro, but they also require a larger blood drop, which can be problematic when you are just starting out.
Whichever you pick, make sure you get the corresponding strip. Personally, we use the Confirm with the Confirm/Micro strips ($35.88 for 100 strips).
