- The up-to-9-litre yield is a listing claim, not a guaranteed amount. Actual yield depends on how much syrup is used. Check the selected listing's expiry date, as customer feedback reports mixed experiences with expiry dates and the purchase experience. The listing describes the product as diet and sugar-free, but also labels its sweetness as "Not Sweet". These descriptions do not establish a nutritional profile beyond the claims provided.

## A good fit for

- SodaStream owners looking for diet tonic syrup to add after carbonating water.
- Buyers who want a multi-bottle supply for tonic drinks and gin mixers.

These reports make the syrup a plausible choice for buyers wanting tonic to mix at home, while the listing's claimed yield depends on how much syrup is used.
