I just wanted to pick up an inexpensive cuff to use for a simple physical exam class and practical exams. I was unsure what I'd get, but my expectations were exceeded.I just threw it on my arm and took my only blood-pressure and everything seems good to go. Pumps up very quickly. Cuff is perfect size to occlude the artery, but leave enough space to still fit the diaphragm of the scope on the arm without having to wrestle with it too much.I spent the previous week borrowing my classmates $80 Welch-Allyn cuff and though there are structural differences between the two, I can take a pressure all the sameWill update if there are any failures with the cuff, bulb, or manometer.
