GEMFUL Travel Coffee Mug Stainless Steel Vacuum Ice and Hot Drinks Insulated Tumbler for Home Office Outdoor Works, 510ml, Blue

Excellent product, leak-free, keeps items hot for hours and easy to clean and drink from

Good Quality product. As advertised.

I liked the black colour so it’s easy to clean and maintain, the mug is leak proof I bought the bigger one because didn’t find much difference in the price comparatively But I suggest to buy the regular size if you drink in normal portions as it’s convenient to sip from Otherwise good travel mug and can use it at your desk while studying it keeps the drinks hot and cold for a long time

Very pleased with my new cup. Very elegant and easy to clean and use. Keeps the temperature for a couple of hours.

The *GEMFUL Travel Mug* looks sleek and feels sturdy, but honestly, it doesn't keep drinks hot or cold as long as I expected. My coffee goes lukewarm faster than other tumblers I've used. The lid works fine, no leaks, but the insulation just isn't strong enough. **3/5 stars** ⭐⭐⭐ (Okay for short trips, but not for all-day temp control)

Poor heat retention: Despite the product description claiming vacuum insulation, it loses heat much faster than expected — hot drinks cool down quickly and don’t stay hot for very long (much less than advertised).  • ⚠️ Rust issues: After only two or three uses, noticeable rust began to form on the stainless steel surface, which is disappointing for a product marketed as durable and rust-resistant. This raises concerns about the long-term durability and quality of the materials. Overall, the mug does not live up to the expectations set by its marketing, especially when it comes to keeping drinks hot and resisting corrosion.

it met my expectations

Just perfect for me
