My wife never has high blood pressure and this says she does.
It is over 15 mmHg off on readings and that is a serious issue.  I went to my Dr to have it checked and verified this device is not accurate for reading blood pressure.  You are mostly paying for the bag (That mine ripped the first time the velcro was undone on the side. Which is not a big deal, but I wanted to measure my blood pressure and this doesn't work!.)
I have tried contacting customer service about a possible faulty measuring 'Sphygmomanometer' and to get a replacement.  They never contacted me back and that has been over a week now.
I am definately going to return this product and report to Amazon.com customer service and satisfaction because this item is not up to PRIME standards and is falsely rated.

Proceed with extreme Caution!  They are selling product in violation of ToS by adding a disclaimer that says:

****Basically they are saying they can send you whatever they want and don't read or look at any of the pictures or product information***  Did not receive correct device I ordered and was not properly calibrated.

There is no 0 on device to even have it calibrated.  You can't calibrate it at 20mmHg without have another accurate device.
 I expect a full refund and will be sending this inaccurate item back if I don't have from you and contacting Amazon.com about your "legal disclaimer" which violates Seller account policy and constitutes as fraudulent item being sold.  There is also a leak somewhere because Air is always flowing out with tubes connected properly and have had a Doctor examine this device for accuracy and it has failed on all 4 tests preformed by a professional. Doctor and R.N at our primary care physician. It reads my blood pressure at 162/78 which is ridiculous.  Get what you pay for.

Also stethoscope did preform as expected.  I could hear everything fine and my heart beat as expected, but the Cuff is cheaply made and leaking after the 3rd or 4th use.
