I am a Nurse, so I know blood pressure and how to measure it. DO NOT buy ANY wrist measuring machine no matter what the price...they are inaccurate and true BP readings need to be taken from the upper arm. I reviewed all Omron upper arm 3, 5, 7, and 10+ Series machines. The Series 7 is my top choice mainly for the superior cuff you get with this (also comes in the 10+ series). The 3 and 5 Series have the standard wraparound cuff that we have used for decades and it is easy to not set it up correctly on the arm if you don't know what you are doing. Getting the cuff too loose or too tight gives inaccurate readings. This new patented cuff by Omron is a joy to work with. Just slip it up the arm, align the blue strip with your middle finger, then wrap the Velcro strap around to snug it down. It gets the tension just right and any novice can use this like a pro. It also has a screen icon that verifies when the cuff is on properly or not...very nice! I have gotten consistently accurate readings with this cuff after dozens of uses. That is the MOST important feature of any machine...it better be accurate or it is garbage. With that being said, another nice feature of this machine is it comes with a power cord in addition to battery power, so you can go portable or anchor it down near a plug. The memory features are nice for keeping track of your readings at home and you get separate morning/evening tracking. Just be sure to take your pressure twice a day in those time ranges. This machine DOES NOT have the two user function, even though it is advertised as such. This is no big deal, but if you have more than one person using this machine, you are better off keeping a notebook of your readings, instead of several users filling the memory with mixed readings. Another small fault is the tube from the machine to cuff is very short and you have to position everything carefully before taking any reading so the tube is not stretched or pinched. Finally, at this price, a storage case should be included to protect and allow easy carry of the machine, cuff, and power cord. These small faults are why I gave this machine four stars, but I will give it five stars on it's accuracy and ease of use which is critically important. The Series 10+ machine has a couple more bells and whistles, but mechanically operates the exact same way this machine does. So that is why this Nurse recommends the Omron Series 7 as the best of the bunch.
