Riester - Mobile Aneroid Sphygmomanometer ri-san Latex Free - - Slate Grey

I do a lot of physicals and this is my go-to blood pressure cuff. I also like the MDF brand but I wanted a single hand operated Sphygmo. This one works great with one small exception...once 60% of the air is out of the cuff you still have about 40% that won't come out unless you squeeze the cuff with your hand. A little annoying if you're like me and doing 10-20 physicals a day. Other than that, it works great.
