I preferred to buy the Medisana MTP Pro instead of the Medisana MTP (which I have already purchased for my parents), considering that it is worth spending a little more money for something that appears as an upgrade. Unfortunately, it has a very large cuff size (30-42cm while the classic one is 22-32cm), something that should be emphatically highlighted in the product description as it is not intended for the average user/patient (attention to the edit below - this only happens in a specific store while the representative informed me that it includes the regular cuff size).
Indeed, when I needed to use it for my wife two months after the purchase, unfortunately, it cannot take a measurement as either the cuff comes off (the scratch) due to the minimal contact surface, or it constantly shows an Error indication in the measurements. Only then did I search and realize that there is such a huge difference in cuff size in a product that simply differs with the Pro indication from the regular MTP (which includes the normal cuff size).
I recommend to prospective buyers to first confirm that this specific size fits them and then proceed with the purchase.

Edit 26/08/2019: After a relevant communication with the representative, I found out that they include the "regular" cuff 22-32cm in the packaging, while if they include the 30-42cm cuff, it has a sticker outside the box saying "large cuff" (besides, the enclosed user manual states a cuff size of 22-32 while it shows the 32-42 as an additional accessory). Unfortunately, only this specific store from which I purchased the product sells the large cuff without the relevant prominent labeling (either in the object description or outside the box as informed by the representative). I will contact this specific store and will come back to evaluate the product (for now, I have evaluated that I cannot express an opinion in all the provided fields).
