BeurerBM 81 easyLock Upper Arm Blood Pressure Monitor, clinically validated, cuff with simple twist lock, no tubes or cables, gentle and fast measurement, with app connection

Works fine. No need to mess around trying to tighten a cuff with one hand. Just slips on and you tighten with the dial. Easy.

Seems good and to give a good reading. I do tend to leave the back of the battery coveroff when using. This is only me, but I feel that if it for some reason started working wrongthe pressure on your arm could continue to increase and you have no way of stopping it unlessyou can grab hold of those batteries and pull them out. It does have a release pull onit which would probably work. Maybe I watch to many films. 😂On a plus side it does tell you if it's on wrong for a reading and you haven't got any tubesto place in the right area.FOLLOW UP.It staeted to give of strange symbals not the battery, and seemed to add to much pressure that made it uncomfortable and painfull to use if it showed a proper reading, getting worried it may continue to inflat rather than stop when it shouldm so sent back, the amount of pain it caused also if it did read correct meant it wasn't something you would want to use for regular check on bp

I bought this to take on holiday, while I was having issues with another device I was trying and was planning to return. This is actually a lot bigger than I anticipated, but it works well and is easier to use than the Velcro straps. It’s a tube you put your arm in, then turn a dial to tighten around your arm.Not sure how long the tightening mechanism will last, it uses nylon chord, which may be a weak spot, but it seems to be holding out.It would be better if this had a USB rechargeable battery instead of 4xAAAs. Not managed to get the app to work with the device, as I’d need to set up an account (entering my details. More usernames and passwords. Why does the company need my BP readings ?), I couldn’t be bothered with that. Other devices just link with my phone.But the readings seem accurate and it’s easy to fit. I’m not sure it would be durable. Have used it for 3 months without an issue, so willing to give it the benefit of the doubt.
