I am having the exact same issues with mine and the variance is also consistent with yours. Mine was also measuring 15 points on systolic and diastolic when compared to Dr’s office. We had the same result when testing the device on another person. Sadly I was put on meds in large part to the daily readings I was providing the doctor prior to surgery. During the surgery my blood pressure dropped dangerously low and I was kept in critical care to recover from the low blood pressure during surgery. I am torn about using the device because I don’t know what to trust.

I just purchased devise after cking reviews. So far way over doctors results. I lije unit. However if i cant trust results then defeats purpose o buying one. Ill try different waysxto use it on my arm.customer service busy as is understandable. Too badd.

I have the exact same issue: that being that my doctor's checks (two over a 20-minute span) were 126/80 and 130/80. The BPM Connect is showing 150-170/100 on average. I have sent a note via the Contact Us link to ask them to send me a replacement since it's under warranty. What a bummer as I really like the machine.

Out of the box, I‘ve had the same issue 189-119. I’m almost dead according to these readings. Also, with proper use, the cuff tightens too hard to the point it almost bruised my wife. I felt the pain but the velcro started to pop open before it determined it had a good read.
Since there is no way to recalibrate, I need Customer Support to provide the instructions to return and receive a full refund.
I am used to high quality products by Withings. This one looks nice but made poorly. Any of the Withings BPM products should have a way to recalibrate.
Thanks.

Follow up.  First, the Withings support folks have been incredibly polite and somewhat responsive.  after doing a factory reset and reinstall, it seems closer to what i expect.  The readings are still higher than the ones that i get in my Doctors office, but at least they are down to 140/90 instead of 170/100.

with that said, I have to agree with the other users: it is difficult to trust the information I am getting from the device when it seems to be consistently higher than what I get when it is tested by a medical professional.  

I had the same experience with incorrect reading. My sbp was high 90s.  But after two months, the device would show 130s. I did factory reset. It's back to high 90s. I noticed some residual air in the cuff before. Maybe it has something to do with it.  

I am experiencing exactly the same issues. First reading is incredibly high. Second reading is better but still high. My previous experience with previous withings monitor was much more accurate and consistent.

I just found out that mine is reading much higher then the actual, or should I say doctors office. What is up with this and what can I do about it.

Same!!  My readings are more than 20 points higher with the Withings device than any other device!  This is really dangerous because during COVID when we couldn't have in-person visits, my Dr was relying on my readings to get my dosing right - and the whole time my BP was actually 20 points lower than we thought!  Finally brought the device into the Dr office with me, and she took 2 readings with her own devices, and one with my Withings, and proved the Withings device is completely inaccurate.  Can't believe they can sell this garbage as a reliable health care device!

After getting my blood pressure checked at the doctor's office a few days ago, I now also believe that my BPM Connect is reading ~10pts too high on diastolic. Systolic seems closer. I will try to reset and see if readings get closer to doctor's office.

I'm seeing high readings too, particularly the diastolic, which is coming in 30 points over a doctor's manual reading and another device at the same time. Bad unit? Withings Support, please chime in here! I want to build on your ecosystem, but if we can't trust your devices OR your support what can we do?

My blood pressure readings are way too high. This is the second blood pressure monitor I tried. How can the bpm be calibrated?

Dont depend on the reading from the BPM. It is absolute nonsense

I'm having issues with inaccurate readings too.  Similar to all the previous comments.  Ranging about 20points too high for Systolic.  

Took it to my regular doctors and he took 3 readings using different methods. 

BPM Connect was way off at 150+ whereas his other readings were in the 120 range. 

Looking back over my BP history for the past 5 years, the doctors data correlates to a 120/130 systolic so neither I nor the doctor trust the BPM Connect.

Very disappointing so far.  Am waiting for a response to feedback I emailed earlier today.

I like the unit so I hope there is a calibration or firmware fix.
