Quite potentially due to abuse, but that's just a guess.They had them on base for a while, and just as I assumed they would, discontinued them after a year or so, grrrrrr.
No, I think they just got the soda streams in for a while and then people stopped buying them... the space is limited in the PX/BX, so on to the next big seller...Quite potentially due to abuse, but that's just a guess.
It would've been best for them to keep them behind the counter or locked up like other products, for legitimate use.
