Vive Precision Smart Wrist Blood Pressure Monitor – Digital Automatic Accurate BP Cuff Machine for Irregular Heartbeat & Heart Rate Detection at Home – Portable Wireless Display for Adults, Pregnancy

Easy To Use and Fast To Learn
Works great, really easy to set up and understand how to use. Being my upper arm is real big from being overweight I have had issues with getting an accurate reading, I am going to have some one help me do it for I position the cuff but the upper part cannot close as tight as the lower part and is either too loose or too tight once reading has started. I still like it very much for there is nothing else I can use unless I would have went with a wrist one and feel I can get a more accurate reading having on the upper arm. The batteries went dead fast so will buy my own and sure will last a lot longer then the ones with it. The reading light is very good, easy to read and large letters and numbers. I have had no problems with it and have seen very good reviews on this more then any of the others with a large cuff. Delivery was fast and the box was heavy duty with info and warranty in it, I keep mine setting in the box when not in use. Highly recommend this to all to buy.

Accurate and easy to use!
This blood pressure monitor is excellent! The readings are consistent and match what I get at my doctor’s office. The digital display is large and clear, and the cuff fits comfortably on my arm. Easy one-button operation and it stores previous readings for tracking. Great value for a reliable home monitoring system. My doctor is pleased with the accuracy of my home readings!

Inaccurate, NO calibration inst. provided. UPDATE: Working w/seller to resolve this issue, stay tuned!
At first I was impressed by the ease of use. This thing is very simple. READ the manual tho. You have to do that, there are a few things you need to know, but when you do, it’s very easy to use.Unfortunately, the accuracy is entirely too far off. I took this thing along to my doctor’s office at my next appt. and compared it -five times- to their calibrated and certified accurate BP machines. This thing was always reading 15% to 20% low. I could have excused 2%, maybe even 3% inaccuracy, but this thing’s digital like the one in the doc’s orifice, and it’s made with virtually the same components. I don”t believe this device was individually calibrated to any sort of standard before packaging, and nowhere in the manual do I find any calibration info or instructions. This to me is a glaring oversight. A medical product, even a cheap one, should meet a minimum standard and provide both evidence of calibration and instruction for user calibration to a known standard, like the certified calibrated machines in your doctor’s orifice. They should calibrate these carefully before packaging and indicate in the Amazon info that this is done. I’d easily have paid a lilbit more $ for one of these that has been factory calibrated to +/- 1%-2% accuracy. I feel that’s a reasonable expectation for the item and the price paid. Given the inaccuracy of this thing, the lack of any sort of calibration instructions, and the price asked, I rate this one star.UPDATE 1-I received a message from the seller, they sent another unit and advised I can keep the old one. The new unit readings are a bit more varied than the first one. That first one read consistently low, though varied. The new one reads high, and a lilbit more varied. I opened the old one, and after careful examination I find no adjustable components inside. There’s no variable caps or trimmer pots, nothing I can find/change/adjust to bring it’s innards any closer to being accurate.The fire department nearby was happy to help me compare the thing to theirs, more time to devote to me than my doc’s orifice will. We spent a couple of hours testing it against their own BP devices. Our methodology covered the reasonable comparisons, and we just found this thing lacking credibility. Our conclusion(s)…If you want to determine that you have blood pressure, this device will competently do that. If you’re seeking a reasonable degree of accuracy, it will not. FWIW, they’ve had a few others bring their consumer-grade BP devices in to test, and some are better, some worse.Your mileage may vary.UPDATE 2- I’ve received further words from the seller. They emailed me with a link to contact them. I would have already done so, but unfortunately, the provided link was truncated, ending in …’s, making it useless. Dagnabbit.Dear seller, if you have news I can use, please contact me again. Include a COMPLETE link or email address, and verify it’s complete and working before sending it to me. I’d provide you my direct email, but I can’t do that -here-, sorry. I’m happy to work with you to solve this problem, maybe together we can fix this accuracy issue, maybe even make YOUR BP machine the most accurate consumer-grade BP device on Amazon. I’ll rewrite this entire review to reflect this issue, and its resolution if possible. It’s in everyone’s best interest for me to be fair and honest, and so far you(seller) have also tried to do that. Thanks for being interested/involved in fixing this, for me and for all others with HBP.
