# mommore MM3402 Kids Insulated Tumbler, 12 oz

The mommore MM3402 kids tumbler holds 12 ounces and combines a stainless-steel, double-wall vacuum-insulated body with a removable straw. Its compact capacity and dishwasher-safe components suit everyday drinks, while the listing's insulation-time estimates are claims rather than verified performance.

## Before you buy

- The listing estimates warm-drink retention at approximately 3–5 hours and cold-drink retention at about 5-12 hours. Treat these as manufacturer claims, not guaranteed results. It also describes the bottle as both spill-proof and spill-resistant, so the degree of leak protection is not confirmed.

- Buyers who want a reusable stainless-steel cup with dishwasher-safe parts.

## Less suited to

- People who need a stated, independently verified leakproof guarantee or tested temperature-retention performance.
- Buyers needing a larger-capacity bottle than 12 ounces.

## Customer feedback

Aggregate ratings lean positive, with most ratings in the highest category, but a smaller share are low ratings. With no written customer-feedback summary available, the ratings do not identify specific strengths, complaints, or reasons. They offer limited guidance on whether the straw, cleaning, or insulation suits a particular routine.

## Frequently asked questions

### How much does this tumbler hold?
The listed capacity is 12 ounces.
### Can the parts be cleaned in a dishwasher?
The listing says the straw, lid, and cup are dishwasher safe and can be taken apart for cleaning.
### How long does it keep drinks warm or cold?
The listing estimates warm drinks stay warm for approximately 3–5 hours and cold drinks stay cold for about 5-12 hours. These are manufacturer claims, not verified guarantees.
### Is the bottle guaranteed not to leak?
The listing uses both “spill-proof” and “spill-resistant” wording, so it does not clearly establish a leakproof guarantee.
