I find the supplied cuff is very hard to use. I bought the monitor for a visually-disabled person, and that makes the use of the cuff even more of a problem. I am trying to get a cuff with the same size of cuff intake connector but one that is easier to fix on the arm. I will not give the cuff your company provided to my visually-impaired friend. I even had the local pharmacist place the cuff on me to confirm that it is not easy to set up the cuff. She got an incredible measurement result. She then used the pharmacist's monitor on me, and got credible, repeatable results with the pharmacy's cuff.
