Money well spent!!! Very accurate bpm, especially for people who has a giant arm, this is it. The material of the sleeve is better than the Welch Allyn spot vital unit.You dont want a sleeve that leaks, it takes away its purpose.Another key to get accurate reading is that not to measure right one exercise, had a meal. Sitting upright position, with both feet flat on ground, back against the chair, try to maintain a steady breathing, all of these help an accurate reading.I took this machine to medical clinic and hospital to compare the accuracy, I found out the different results due to the user, if the medical staff applied the sleeve too loose, of course the reading is lower.Recently been to hospital, same brand of bpm, different physicians measured my pb different readings under the same hospital.In short, I trust this machine, user friendly, comes with great feature where one can connect to pc, and operate with option batteries or adapter.
