Doctor had asked me to track my daily blood pressure to see if my HP medicine was working as needed. Monitor is easy to use,numbers are easy to read and stores in memory to help keep track of BP readings. Works really well for my purposes. Had this monitor for close to a year and it's still working well. Zero problems. Would definitely purchase again,

Been using cuff style blood pressure monitors for the past 10 years always purchased them from the local big chain retailer, always had issues with accuracy if the cuff is to loose or to tight the reading is way off, constant error issues, decided to give this wrist style monitor a try as it was inexpensive, ends up being the best monitor I've had thus far, gives accurate readings just about every time verses the cuff style, the learning curve with this monitor is it has to be at the same level as your heart, don't worry about resting your arm on anything simply place the monitors face at the same level as your heart or lay your left arm across your chest with the monitor over your heart and your readings should be pretty accurate every time, I used to have to take several readings with those cuff style monitors not anymore, 2 readings max roughly 10 minutes apart and done, only one way to put the monitor on, no fiddling or fine tuning adjustments needed.
Would definitely recommend and I would definitely purchase again when the time comes.

**Update**:
Okay after over a year of use what do I still think of this unit, well it's been really accurate, except I get the occasional off readings that can't be explained, what do I mean.?, from time to time not very often, I'll get these real low readings of 64 - 74 systolic, diastolic readings stay pretty constant as does the heart rate, a little concerning and yes it drives the anxiety upwards, each time it's happened I've tried twisting the meter, re-positioning the meter and would then see 90 - 110 systolic and the other readings would be normal, at those points I'd remove the meter completely and put the meter back on recheck positioning of my arm make sure I'm sitting properly and then receive readings of 150 or more systolic, the low readings one would be feeling, and I wasn't feeling anything that would indicate I was experiencing hypo blood pressure, waiting around 30 minutes for the anxiety to lift everything would come back to normal, I've checked the batteries and what one can see but have no explanations towards these odd readings, I still think it's a great monitor but just beware and don't panic when you see these off readings, give it time and recheck or if you have a cuff monitor available check that against this and see what comes from that, I know these wrist monitors can get thrown off by the least little things, I still believe it's got something to do with the batteries when they get to a certain level of discharge.
As for me the other situation I suffer from is a ton off nerve damage throughout my upper body that tends to run through my arms and I don't know if that's having an affect, and any of those concerned, I have gone to the ER before and been placed on the hospitals monitor and they can never find anything wrong, so I'm not sure what to say in this situation might just be me, but I felt it was worth an Update.
Otherwise I'd say this monitor is accurate 90% of the time, I'd still purchase again if something happened to this monitor, as it did work perfectly for the first year of ownership and daily usage.
Anyone that is still concerned, I had a Unnecessary Catheter-Ablation done at the end of 2015 the doctor mistook my hyperthyroid condition for a heart related issue, so due to this unnecessary surgery I under went, I have a "Loopback" recorder in my chest and that has yet to ever catch one of these episodes, hence why I'm not in such a overreaction of the whole situation.

While I like the price and small size, the reality is that an inaccurate blood pressure monitor is pretty much worthless. I followed the instructions carefully, but when I took 3 readings back to back they varied wildly--by as much as 10-20%. I borrowed a friend's high dollar Omron Series 7 monitor that he has verified with his doctor for accuracy, and 3 back to back readings with that monitor was only a few points off.

I would not buy this product again.

This blood pressure monitor for the wrist is exactly what I was looking for. A small, fast, easy-to-read monitor for home use. It's accurate as it matched what my doctor's office numbers when I took it in to the office with me. As a COPD patient, this allows me to monitor my vitals at home for early detection of exacerbations.

The monitor arrived well packaged and on the estimated due date. I would purchase from this seller again.

Excellent! So quick, light and easy to use. Very accurate, too. I like that readings are stored in memory, so you are able to check back and compare, if needed. Highly recommend this for price and quality!
