## At a glance

- The manufacturer describes the set as sugar-free and says the cubes contain natural caffeine from ingredients including guarana, guayusa and kola nut.
- Dissolve one cube in still or sparkling water. The suggested water volume is 400–600 ml.
- The set includes blackberry, mango and cherry flavour options.

## Pros

- Three flavours in one 36-cube set give buyers alternatives without choosing a single flavour.
- Cubes can be added to still or sparkling water, avoiding the need to buy a ready-mixed drink.
- The stated caffeine content makes the per-cube serving easier to gauge than an unspecified caffeine blend.

## Cons

- This is a mix-in product that needs water and time to dissolve, rather than a ready-to-drink beverage.
- The listing does not provide an exact calorie figure despite describing the drink as low calorie.

## Before you buy

- The listing title says 90 mg natural caffeine, while the product details describe each cube as containing around 90mg. Treat the quantity as approximate. The title also claims vitamin C and B, but the supplied product details do not specify vitamin amounts. The listing calls the drink fizzy while preparation allows still or sparkling water, so the drink's fizz depends on the water used. It describes the set as low calorie but supplies no calorie figure. Use the suggested 400–600 ml of water per cube.

## A good fit for

- Buyers who prefer a mix of blackberry, mango and cherry flavours and can prepare each drink when needed.

## Less suited to

- Anyone looking for a ready-to-drink beverage or a caffeine-free option.
- Buyers who need a confirmed calorie amount or quantified vitamin content before purchasing.

## Customer feedback

Customer feedback is positive about the flavour mix, particularly berry and cherry, and some say the cubes help them drink more water. Caffeine content and sugar-free formulation are also mentioned favourably. Value opinions are mixed, with some finding the set worthwhile and others considering it overpriced. These are reported perceptions, not confirmation of the listing's claims. The approximate caffeine amount and 36-cube format may help buyers judge fit, while the lack of an exact calorie figure may matter to those comparing drinks closely.
