SodaStream Classics Diet Tonic Sparkling Drink Mix 440ml 1 "Shocked" Mr Furnell 26 February 2016 Bought a bottle of this tonic yesterday. I realised the bottle was a new design, but appalled to find out when I got home and had a chance to compare with the old bottle that the quantity had reduced by 60ml and the price increased by £0.70. This equates to a 38% price increase. I think my Sodastream will be going back into the loft as the taste wasn't that brilliant either! A note from the team Thank you for placing your review. We're sorry you're disappointed with the size of the bottle and the taste wasn't to your liking. We appreciate your feedback and we'll pass this forward to our buying colleagues to look in to further.
