For the last few weeks I have been using the iHealth Blood Pressure Dock. This is the first product of this type that I have actually used so I don’t have any comparison products to judge it against. But I can say its one of the easiest things to use right out of the box (My pics are at the end of the review)
The kit comes with the dock, instructions, power USB cable for dock, and your choice (out of two sizes) of arm cuff. The free app required needs a minimum of iOS 3.0 or greater (There was an app update this month). The dock itself contains a rechargeable battery that powers the blood pressure system / cuff.
