Unfortunately, every reading was crazy high. We finally figured out that the monitor was twenty points higher than it should have been. We took the monitor to a doctor's appointment where they confirmed that the Index readings were too high and didn't match the readings in the office. In addition, we have an Omron BP monitor that also had normal readings that matched the doctor's office readings. The concern with the Index stating that our blood pressure was twenty points higher, could have led to unnecessary mediction. While we really liked the idea of the Index, the device didn't work as advertised.

The good: The unit seems well built and accurate. It is nice to have this information in the app, easy to establish a baseline and watch for trends. The bad: I can not connect a second user. This should be possible and the process looks easy. However the second user never gets his/hers results uploaded to Garmin. It appears to be a WiFi upload problem and has caused me to spend way to much time in this. I still have not got it working. So if you buy this to share with someone, expect problems. Maybe unsolvable problems.

The BP unit works great 5 stars. The initial setup was easy. The invitation setup was a little tougher. It took a few hours of setting up and resetting up to get it to connect correctly for both users. Some of it may be user error but the on-line instructions seem to be different based on which link for help you select. Now that it is connected to both users it works fine. The Bluetooth connection work well but I'm not sure the wireless network connection works as well. I'd recommend the unit and the fact I don't have to write the data in a book anymore is nice.

I leave this unit in our company break room where anyone can use it. Most people in my company have Garmin products (Watches, EDGE, etc.) and already use Connect so it was easy to add the BPM to our WIFI network and I invited the various users to attach to it. We all use it daily and log the data into our own Connect accounts. You just select the user with the top button. It couldn't be easier!

At the hospital I had a nurse check my existing BPM and it was dead on. When I received my Index BPM it consistently read about 10 mm high for sys and 7 mm high for dia compared with my validated BPM. The pulse was accurate. I then reset the new Index unit and tried again to see if there was some problem that a reset would clear. No change still about 10 units high

I bought this to replace my old monitor that needed to plug into the wall. It is so much more convenient to be able to sit anywhere I want rather than needing to be right near an outlet. It's also small enough that I can bring it with me when I travel. The fact that it automatically syncs with Garmin Connect is a super bonus. Love it!

Purchased both the scale and BPM, however the BPM Index device we could never get it to activate. After numerous attempts and frustration we were finally able to "exchange" it which we would have thought we should get a "new" device one since it never would activate, but we received a refurbished device as a replacement of a brand new device. I tried setting up the replacement (refurbished...) and the display is so faint you cant read it, but yet again it will not advance through set up. Now dealing with trying to get a full refund which has been difficult and still not resolved.....

I do not suffer from high or low blood pressure since getting myself in shape but as part of my overall fitness regime I have been monitoring my BP for a while now. As an avid Garmin user, this product's launch was timely for me and since I received it, has not failed me. In concert with Garmin Connect, I now have a full history of my BP over a period of time which I can share seamlessly with my Doctor. Awesome product.

Disappointing device. The device "forgets" users periodically (once a month), and I have drop the device and re-add it to my account to get it to work again. When it does work, it is difficult to adjust and often generates different numbers between my left and right arm.

I am hoping that I got a bad BPM - sent it back and hopefully new one will work. Sent it back since it was consistently reading 15-20 points higher than what I get from medical professionals taking it manually. Will try the replacement - hopefully it reports more accurately as I love Garmin products.
