This set is very special, because in addition to the cylinder is obtained even a 1L PET bottle it. Prices change constantly so, but currently this set is really inexpensive. If you look at the individual prices, you get here the PET bottle quasi almost on top of it for nothing more. But as I said, the prices are constantly changing, so I would check again before the purchase decision. The individual cylinders without the plastic bottle you get here too: SodaStream Soda Club Reserve cylinder Co2 60L ORIGINAL FULL 425g Co2
The cylinder weighs just over a kilo. Whether filled or empty makes little difference. A new bottle is protected on the head with a plastic band and a plastic plug. The expiration date is printed on this plastic stopper and is always at my bottle over 2 years. Per cylinder should be able to bubble up to 60L water. This number, however, is actually fictitious. Only those who make do with one or two Spudelstößen per 1L bottle, also comes actually to 60 liters. The reality is somewhat different. For example, I've bought the SodaStream, as I like to drink well water sparkling table. Medium I do not like, it must be lively. When SodaStream you have to push the button for easy tangy effervescent 3-5 times. I did and found that I bring it to just 36-42 liters per cylinder statistics over several weeks. Noted again - with sparkling soda! For medium bubble of course you get back much more.
For PET bottle there's not much to say. Who SodaStream used, who knows that the cylinders are fitted with a best before date. In my new bottles are loosely 2 year olds. After 2 years of use, it is recommended to replace the bottles with new ones. Also makes sense, because it is, after all, what is claimed and no plastic glass. The PET bottles must not be washed in the dishwasher, and only lukewarm by hand. There are also expensive dishwasher-safe PET bottles, but with whom I had very bad experience.
Conclusion: cylinder and PET bottle for the SodaStream, a currently very inexpensive package.
