I recently purchased three refill CO2 bottles from Bed Bath and Beyond, at different times, and discovered that they did not fill nearly the number of bottles. The two previous ones filled only about 10 bottles before they ran out.
The last one I got was, for all practical purposes, empty. It filled only four bottles and just barely.
If this is a Soda Stream trend, then there really is no financial reason to continue purchasing refills. If it is a Bed Bath and Beyond issue, I will try a refill from another store, but I fear, given the number of deficient bottles, it is Soda Stream getting greedy - or financially unstable.
Reason of review: Bad quality.
Monetary Loss: $45.
I liked: Convenience of making own carbonated water.
I didn't like: Deficient co2 bottle refills.
