This is an excellent item. I find I drink more water using the soda stream.

Work and for me casual user last quite a long time

No instructions on how to get credit, what a waste of money

I purchased the "SodaStream CO2 Gas Refill Pack - 2 Cylinders, Pink CQC System - Use box to return your... blah blah blah you gets some munies back" I am about to send my 2 empty bottles in and I like this product even more now that they are empty. Why? Because I'm insane. Just kidding, they include everything you need to EASILY return the used cylinders!! Carbonation: works just as well as the original Ease of use: the bottles are insanely easy to add and remove, having two in the box is wonderful... always nice to have a spare so you can always enjoy your fizzies. Bottles look the same as the original The Box: "What's in the BOooOoxa?!?!" No severed head of your loved ones here. Excellent structure, keeps the bottles from knocking around into each other without an excessive and wasteful use of materials. Also, love the big READ ME YOU DUMMY "keep the box!" message, because my lazy self probably would have tossed it w/out reading if it wasn't so IN YOUR FACE! Maybe I wouldn't have... it is quite orderly and efficent but.. more than likely I would have tossed it and the first empty bottle. Return process: In my opinion so far, flawless. The steps are simple and easy to grasp, perfect again for my lazy/efficent personality type. I get to feel more hippy/green because I'm actually recycling Vs. putting stuff in a different garbage can that will end up in the dump or ocean or another country anyway... but I still do it because MAYBE! Gotta have hope that at least SOME of it makes it to being repurposed... Sorry, side quested there... back to the return process, I had zero problems with the website, just make sure you add the -'s from your order number, it found my 2 year old order without issue once I added that. Just put the empty cylinders into the box, rip off the old label, drop it off at UPS with any other returns, make sure you complete the website and return the package within 15 days and done. Easy, green, and a lot less crap in the trash bin to go sit forever. I'm going to go make myself another tasty carbonated beverage with one of my new flavors (wish me luck). Happy fizzing!!

Cylinders work as well expected, but there is a limited time to return the empty cylinders. And there isn't enough time to consume the full ones, so I didn't benefit from the sellers offer to return the empty one's for free.
