Really convenient but some black spots

So much easier to take his blood pressure regularly at the wrist than raising his sleeve.
And then finished paper and pencil, memory and connection to PC is a real plus.
Device very stylish, well finished, and this black is less "medical" than white must.
Moreover it is bright without being dazzling in the dark and the volume level is very low key.
The least it seems energy, (1 set of batteries in 1 week) his two small batteries do not last long.
But especially when changing batteries if luckily you do not lose the memory, we lose against by the time and date and one has to retype all programming, so every week again.
The software is not an example of simplicity and above all is not Mac compatible but it has the merit to exist.
That's why I put only 3 stars although satisfied with its use.
