I am delighted to have it in my possession! I finally have the pleasure of making my carbonated cocktails. Even with orange juice bottle that works. The principle is very simple, everything is provided and cocktail can be kept cool even in the bottle with the supplied plug. There really has everything to make life easier! Gas bottles are recyclable. A thick recipe booklet is included, and it is even with plastic! It will support many handlings. In short, it's really good quality, Mastrad a good brand, but any little thing that I can challenge: there is no greater capacity (it has 75 cl) for that price ...
