It seems good, but the cuff quality is poor. I have only had it since May, and I use it only at my desk (i.e., it is treated gently and I don't travel with it), and the cuff is falling apart. Some of the stitching has come out, and there is a hole in the material near the Velcro. It is accurate (measured accurately compared to my doctor's office twice), and I like having the whole history of the readings on my iPhone and the comparison trends on the machine to look back on. Batteries seem to last a long time (my own, not the ones that come with it). I would likely give it 5 stars if the cuff had not fallen apart so quickly. The seams first started falling apart around September so only 5 months until it started to fall apart.
