The LOP Device (V1.1) is only used to assess Limb Occlusion Pressure (LOP) and works with or without your phone
The LOP Device & Bluetooth Device is primarily engineered for healthcare professionals, for valid, reliable, and swift assessment of Limb Occlusion Pressure (LOP) aka. Arterial Occlusion Pressure (AOP). But whether you are a physical therapist, chiropractor, personal trainer, strength & conditioning coach, or researcher it can be relevant to know your client’s LOP.
The LOP Device has build-in LED display whereas the Bluetooth Device is controlled by an app on your phone or tablet, via standard Bluetooth tech. The Device can swiftly assess LOP as a convenient alternative to handheld Doppler ultrasound, though less time-consuming. That is without any prior training or education You can measure upper and lower body LOP in 30-120 seconds, respectively.
The Bluetooth Device has undergone comprehensive comparative product testing externally at 3 different universities and research facilities (How the Device Works), which verifies its high validity and strong reliability compared to handheld Doppler ultrasound.

The Arm Cuffs V2.1 are simple and cylindrical/straight that fits most individuals

Just as the Arm Cuffs V2.1 the Leg Cuffs V2.1 are cylindrical/straight that fits most individuals
🔩Updates concerning Arm & Leg Cuffs V2.1:
The backside material has undergone a major update. That is a new thicker TPU coated nylon that inhibit sliding of the cuff during exercise and seems to be extremely durable with almost infinite longevity.
The Cu-logo rubber patches are mostly for the looks, but if you get your hands on these You will soon discover it simply makes attachment and particularly detachment of the cuffs more intuitive.
🔩Exclusive improvement for the Leg Cuff V2.1:
To decrease pressure fluctuations during muscle contractions, we have implemented a more flexible internal core material. After testing several prototypes and researching on mechanical properties of different materials, we believe to have discovered a core material and thickness with an excellent blend of both stability, pliability and tensility.
On the hand the Leg Cuff V2.1 simply feels more robust but also a bit softer to the touch.
The air plug has been further reinforced by an external rubber patch with the black protruding logo.
