Good replacement bottles

Since the Sodastream plastic bottles have an expiration date (have a look into the fine print on the bottle, I also can not believe habs), this set of 3 is a good substitute.
Thus, these bottles Consumable materials, come back to after 2 1/2 to 3 years must be replaced. Take into account in all economic calculations with!
Three bottles of 14, as there is nothing to complain about.

The fact that the bottles are not dishwasher safe, is not a problem for me because I always clean by hand with a bottle brush. Hide nice bottles should be clean with the narrow neck in the dishwasher ?? At best, the outside, but not inside ... To clean in between suitable prima baking soda or denture cleaners tabs. The shutter to clean, while I get out the seal (this is best done with a sharp knife, but be careful not to damage the seal). Then clean closure and sealing with washing-up brush or sponge.

A deduction of points there for the "expiry date".
