I purchased wrist style blood pressure monitor model BPM265W. I have 3 wrist monitor for my mom, father-in-law and me, all different brands, but this Gurin so far has higher quality than the other 2 i bought. I'm a nurse and i know medical equipments well, Gurin product has more accuracy with its readings than the other 2 i have. I give this product 5 STARS!
