I have Accu-Chek Aviva and CVS home brand (TRUEtest). Aviva is always 5% to 10% lower than the CVS meter.
I have had Aviva for 2 years and the results are very close to the lab ones. I trust Aviva, not CVS.

I think the CVS homebrand and Walgreens homebrand are made by the same company. I am glad to hear that it is higher than Free Style. My CVS device is always 5% to 10% higher than my Aviva.
