Sodastream My Only Bottle Black 0.5 L Carbonator Bottle 1 Pk

I take this to work with me and it is the perfect size and the strap helps when carrying multiple things at once.

And I've been making xtreme energy and diet xtreme and showing off my soda making skills

very cute little 0.5 liter bottle with a great metal stainless steel cap, it fits perfectly in the top rack of the dishwasher

Love the smaller, take with size. Easy to use, portable and best of all goes in the dishwasher for cleanup!

I was washing my man's My Only Bottle when I noticed a strong smell of mold. While examining the lid. I discovered a design flaw. As in one can not get under the O-ring to properly clean under it. And in this case, it had developed mold. Bleaching it can only clean so much. It would be much easier to clean if the O-ring was designed to come off. Like redesigning the part that holds the strap to screw off the inner center piece.
