Being a nurse, i've used all sorts of makes and models to monitor blood pressure, including the self application type. Most are flawed by poor unstable connectors, tubes too short to reach between patient and device, clumsy to wrap, the air supply knob is either too tight or too loose, or electrical cords too short to be practical, etc. I was hesitant, skeptical and reluctant to pay this much. (I don't mind so much if it just works!)
Now that the OMRON DLX Automatic Comfort Cuff has been in use for almost a month, it has proven it's worth!
All the cords/connections are ample and stable. The reading is accurate and easy to obtain, even one-handed. It stays put when placed on the upper arm above the elbow, is comfortable and easy to complete the velcro closure. The memory allows comparison over a significant period of time and is a handy feature.
I haven't tried to use it on battery power, but it gets my thumbs up!
