This machine is really better than previous ones, because it is easier to use, no need to screw the bottle, simply the "clip" quite easily with a lever. The design is not bad, and a choice of black, white or wood allows to integrate a lot of cooking. Its use is no outlet, so there is not need to puzzle over the cram near an outlet or add an extension cord, can fit it in a corner, or even take her out if we have an outdoor kitchen time for a barbecue. However I find its exorbitant price. I advise anyone who wants to buy it to think carefully about the use it will make because the cost of the machine + the + gas refill different syrups to flavor (perishable pretty quickly, too faster than a soda commercial) + Charging plastic bottle PEP (yes, plastic bottles have an expiration date!) remains high enough in the end, and it will make drink gallons and gallons to monetize all this compared to a commercially available drink. However, for the environment, I do not say, there will always be waste plastic, but much less than with sparkling water and protective plastic film. This requires that the buyer be sure to use it will make.
