The best meter is the one they use at the hospital I forget the brand/modle number. Im sure they can tell you. Cost about $5,000 and $5.00 a test strip.
Walmart has meters for $14.99 and $26 for 100 test strips.
ALL meters sold to the public have to be %20 accurate 90% of the time.
My Best meter is the one the insurance will cover the cost of the test strips.
