Excellent product but impractical instructions

So you must know it, according to your model Senseo, you will need 2 sachets descaling (light, the cheapest models will need 2 bags while the last model like the Twist, one).
The instructions will tell you how much you lift bags (drawing machine), however, it is not very explicit.

Then the descaling cycle is simply done, the machine does all the work. After scaling accomplished, I had the impression that the coffee had a less bitter taste.

This product is perfect, it contains the exact weight for each Senseo machine, you do not bother, Senseo has done the work for you (in the instructions of my coffee, it was written that I had to use 50g of citric acid, honestly I did not feel like bothering me or to buy a large package which I will not know what to do between uses).

For Twist (model I own), 4 = 4 bags scaling cycles so many months of scaling example for others, I can not tell you because the models are not specified (only photo).
