Free Style, One Touch, and lately the
ReliOn sold at WalMart. I think the Relion is the better of all. It's least expensive, at least it's much cheaper than the most popular One Touch, and its lancet system gives me the least pain and it requires the least amount of my blood sample as little as the Freestyle do.
I am referring the RelionMicro monitoring,test, device because there are other cheaper monitoring ,test devices by Relion but require more blood sample.
