I compared my results on the Withings BP against a professional grade WelchAllyn ProBP 3400 series ($900) calibrated handheld blood pressure monitor. The cuff size makes a difference, I used a size 11 (25-34cm) cuff vs. the “one size fits most” built into the Withings BP. I connect the Withings to one arm and the WelchAllyn to my other arm careful to get the same height and arterial alignment. I ran 5 tests then swapped arms and tested 5 more times. Based on the WelchAllyn ProBP it looks like the Withings is the systolic readings were normally within 2pts of accurate but the diastolic readings were off by an average of 4-5 pts. Pulse was within a 1-3 beats. They WelchAllyn was much faster and more accurate because it utilizes the SureBP NIBP measurements that take the readings during cuff inflation vs the Withings that is measuring during deflation. The Hillrom FlexiPort Blood Pressure Cuff is more accurate because it is sized to my arm but it’s meant to be put on my a care giver and putting it on yourself is tricky, but with ability to quickly disconnect the cuff and swap to another cuff it is meant more for a hospital environment. The Withings cuff is easy to put on yourself but I don’t think it is as accurate, also the screen is facing out when you put it on correctly, poor designed choice for an at home blood pressure monitor. But it’s integration with the Withings App is excellent. Overall I’d give it 4.5 stars, with the only negatives being the screen facing outward when correctly placed, the accuracy being a bit off 2-3%, and the cuff tends to constrict more than it need to leading to a slower reading and a bit more painful than necessary. For the price and the App integration I’ll round 4.5 up to a 5 star rating. I also had the original Withings blood pressure cuff I bout 10+ years ago that ran on AAA batteries and this new rechargeable and WiFi version is an order of magnitude better. I even dig how small it rolls up, yeah it’s 5-stars.
