McKesson Digital Blood Pressure Monitor, Automatic Arm Cuff, 1 Ct

This monitor squeezes the life out of your arm, leading to numb hand and fingers in the process. I bought a bigger cuff and the same thing happens. If that's not bad enough the seller will not accept a return or refund you unless the package was unopened or unused, how could you know whether the item worked well without opening the package is beyond me. Be very wary of this seller. I thought I was buying a good monitor and not the cheap ones. I am very disappointed and now I am stuck with an unusable monitor, and still need buy another that is more comfortable. Unfair business practice from this seller in my opinion.
