Perfect! I absolutely love it.
There are enough materials in the starter pack to last for the first months of using the jet, everything is hygienically packed, and I also love the strong plastic box with its contour lining to securely store the jet and the current vial.
(An addirional slot to store the comfort ring would be a bonus in the next generation of the box.)
the handbook is easy to understand, and the application of the jet is the easiest thing ever, although it may seem daunting at first due to the copious instructions. After a few days I could lay aside the handbook and just use the jet.
Although my social security insurance does not pay for it, it is totally worth having the jet, it is painless and more sustainable than throwing away the daily needles and associated plastics waste.
The only thing I would change, especially in the starter set, is the size of the booklets and their font, which is just ridiculously TINY!! Not all elderly people retain their keen eyesight, and not all have the opportunity and skill to download and print the manual on A4 so they can make out what exactly is shown in the drawings.
