This BP devise is so easy to use; and it is quick and accurate. It is small, but easy to handle and manage. The read-out is large and easy to read. The case that is supplied with the unit is a good, protective, durable plastic case that will protect the BP unit well and give me years of service. I found it to be very close to the doctor office reading (within 2 minutes; I didn't expect an exact match, BP can be different from left to right arm). I did hope for a close reading and received it. Very pleased eith this purchase.
