## Before you buy

- Capacity is inconsistent: the title and feature text state 355ml, while product details state 335 Millilitres. Confirm the capacity for the selected listing before buying. The listing describes the valve as both spill-proof and leak-resistant, so treat spill prevention as a claim rather than a guarantee.

## A good fit for

- Toddlers aged 24 months and over who need a handled bottle for nursery, travel or everyday outings.
- Buyers looking for an insulated bottle intended to fit most cup holders.

## Less suited to

- Buyers who need a confirmed capacity before purchase without checking the listing discrepancy.
- Anyone requiring a guaranteed leak-proof container.

## Customer feedback

Aggregate ratings lean positive, with most ratings in the five-star category, but a smaller share falls in lower categories. Without customer-comment details, the reasons for those ratings are unknown. Consider the ratings only as a broad signal, and weigh the bottle’s claimed insulation and carrying features against the unresolved capacity discrepancy.

## Frequently asked questions

### What capacity is this bottle?
The title and feature text say 355ml, but product details say 335 Millilitres. The listing is inconsistent, so confirm the capacity for the selected item.
### What age is it intended for?
