I bought this cuff to replace that which came with the M7 bp meter two or three years ago. The velcro on the old one got to the point where it had almost given up holding to itself so the cuff would fly open when the pump started. I felt this was pretty poor for a machine which professionals use and yet I had only used for myself at irregular intervals - a very light use, in fact.Although the new cuff is essentially the same design, it does appear to have some changes the the construction of the wrap-around so maybe Omron did recognise that the cuff needed improving. Anyway, so far so good but It\'s only been used for about 50 readings - time will tell!What is not so good is that Omron have considerably shortened the air pressure tube which connects the cuff to the machine. If you\'re careful, it\'s no problem but it\'s very easy to make a moderately small sweeping movement with the arm and find the machine being jerked across the table. All for a few pence saving on rubber tube!
