I didn't NEED this product, but I know that my BP isn't perfect. Having a tool to measure it in the mornings made me more conscious of that and more conscious of my health. In terms of accuracy, I feel like it is pretty solid, but I have nothing to judge it against, so I can't be sure if it is perfect. It is Garmin though and I really like their stuff.

I have had this BP monitor for two or three months. It works, but it takes me at least 10 minutes to get the monitor and the watch and the smart phone synchronized. I have had excellent help from the phone support team but after about 30 min per call I get one BP reading and the next day the rabbit trail and the hoops to jump through have returned. Fortunately, I have the old fashioned kind of cuff so I usually end up using that. Why is it impossible for Gramin to put up via YouTube or other easily accessed source, a solution to re-establish connectivity with my Venu2plus? High price, low practicality.

I love Garmin devices and have used their watches for years e.g. I love my Epix. I spent 1-2 frustrating hours trying to get the Index BPM to setup. It insisted on looking for a WiFi. I tried this multiple times, even sitting next to the router. I rebooted it, removed it, reset it, retried it. Nothing. It's useless as designed as cannot get past (FWIW I have two computer science degrees and have worked in software industry for many years. Setting up a blood pressure monitor should not be this hard!). Will try again tomorrow morning but current plan is to return it and buy a different monitor from Omron. Really disappointed with the Gramin Index BPM

I am very unhappy with this device. It was indicating I have hypertension. After visiting my doctor and testing the device against their readings my blood pressure is 30 points lower than the device reading. We took multiple readings and used both arms each time the results were wildly inaccurate. I would not recommend this to anyone.

I consider my arms to be of an average diameter, However, the cuff that goes around the arm has several places where the Velcro is patched together. I am sure this is by design, but there is a Lump where the two materials are sewn together and I have a hard time getting the seam to go through the metal loop - especially one-handed. It can take me a minute or more to get the cuff put on. I consider this a design flaw. Otherwise, I really like the way the Index BPM connects to the internet and my phone. The reports are good and informative and I can share with my wife.

Diastolic pressure always reads high by 10 to 15 mm/Hg I have a hospital AMA approved A&D UM212-BLE it has bluetooth but won't work with your app and an Omron AMA approved BP7450 which does not work with your app. I purchased the Garmin BP because it works nicely with your app. However; the expensive hospital grade A&D monitor aligns closely with the Omron monitor. There is a 10 to 15 degree higher deviation in the Garmin BP monitor. So I won't be using it, as high diastolic pressure can be more worrisome than high systolic pressures. It is disappointing the Garmin unit appears to be inaccurate by such a large amount.

Like all Garmin products this BP is spot on with being extremely well built and durable. Using it is simple, the interface with Garmin Connect works everytime with no human intervention. And the readings as far as I can tell are accurate and consistent.

Received the monitor as a Xmas gift. Love that the data are captured seemlessly in Garmin Connect. It would get five stars from me but the cuff is surprisingly difficult to put on tight enough. Take off a half star for that. I am very happy with the monitor.

Make sure the cuff is seated correctly!! The only issue I had was when the cuff inflated excessively to the point it caused discomfort. This ended up causing an E3 (I think) error which translates to a leak. Repairability is zero. Fortunately, Garmin's return/exchange program is spot on. I like being able to sift through the data via the app.

Wanted to buy a device that would give me accurate results, most of the devices out there don't have properly calibrated microphones, so the diastolic reading is normally too high. As this is FDA certified, the promise is to have more precise readings. Nothing substitute a manual reading, but this is very close to what I get manually, also the convenience of the app to track readings over time is a very good feature for those that need to show it to their doctor. Kudos to Garmin.
