What to know before buying
- The advertised hot and cold temperature-retention times are manufacturer claims, not independently verified performance. The lid is described as splash-proof but explicitly not leakproof, so treat it as unsuitable for spill-free transport.

Customer feedback highlights the design, colour, size and temperature retention as positives, while lid performance is mixed and leakage is a reported concern. That caveat matters because the listing itself says the sliding lid is not leakproof. Feedback is consistent with considering it for upright desk or home use, rather than assuming it is safe to carry loose in a bag.
Positive themes
- Customers praise the design and colour.
- Customers report liking the size and temperature retention.
Negative themes
- Leakage is a reported concern.
Mixed feedback
- Feedback about lid functionality is mixed.
Frequently asked questions
Is the mug leakproof?
No. The listing says the sliding cover helps prevent splashes and heat or cold from escaping, but the lid is not leakproof.
How long does it keep drinks hot or cold?
The manufacturer claims up to 6 hours for hot drinks and 12 hours for cold drinks. These are listing claims rather than independently verified results.
Can it go in the dishwasher or microwave?
No. The listed care instruction is hand wash only, and the details state that it is not microwaveable.
What is the mug made from?
The listed material is stainless steel. The feature text further describes 18/8 stainless steel and a 304 food-grade stainless-steel interior.
