I am in my early 50s and recently been diagnosed with mildly high blood pressure levels by my physician. This is after a lifetime of having perfect blood pressure (and I am in the best physical shape of my life).
I had been planning for quite some time to purchase one of these wireless blood pressure monitors and was keeping an eye on the reviews for the Qardio brand that is also sold on Amazon. However, after all the negative reviews over hardware and sync failures with that brand, I knew I had to look at something else. Actually, what finally drove me to Withings was the 5-star reviews of its app on the iTunes store. There's nothing worse than a strong product that comes with a lousy iOS/Android app. Fortunately, Withings comes through with flying colors in both departments.
Out of box, setup was easy. With batteries already loaded, I simply hit the bluetooth button on the cuff and paired it with my Apple phone. I would recommend that purchasers install the app first, launch it, and have it walk you through the process.
I would also recommend that before you hit the START button on the app and take your first reading, to click on the settings icon on the upper corner of the app and have it automatically take three readings to average out your readings.
I was pleasantly surprised, using the enclosed instruction booklet, how easy it is to place this cuff above the elbow, wrap, and take a reading. It's really effortless. The results are not only sent to my iOS device, but readings are logged within the app and can easily be shared or emailed to my physician.
Have not had to change the batteries yet, so I don't know how difficult that process will be. There is a screw at the bottom of the cuff tube to access the batteries, though I am concerned about it becoming stripped over time. I would be very, very gentle with any coin used to open it.
I also, at the time of purchase of this Blood Pressure monitor, put the Withings Body Scale in my cart. At the last minute, I removed it due to a few negative reviews and the mention that there is no customer support from this company. That is concerning. However, now that I have seen the Withings app in action and the fact that it supports all their fitness products, I have gone ahead and ordered the body scale. It's kind of cool that I can track my weight gain/loss and blood pressure numbers all in one app, sent wirelessly, without me having to do anything than just use the products.
