Design stainless perfect and very easy to use. The capacity of 75cl container deserved to be a little more important especially as each use requires the use of a CO2 cartridge. Wide selection of cocktail recipes in a cardboard booklet designed as a paint swatch, in French and English, elegantly illustrated, very solid and durable. Easy to store in the refrigerator for preparations requiring prolonged gasification process. The bubbles are fine and the drinks all seemed very refined on. Excellent product to impress your friends with refreshments coming out of the ordinary. Small flat for cartridges that have cost just under 8 euros for a batch of 10. Otherwise, no complaints!
