Overall performance of unit is
Overall performance of unit is a disappointment. Start day with bp check@143/92,do again. Next read@138/86.Third read way different. Take meds, wait 1/2 hr or more & take again. Same erratic readouts but in safe range & need to average them. Final read 123/77. Do this 4 - 5 times daily in attempt to avoid mi or tia At least better than none at all which would be dangerous.
