The listing says it keeps drinks hot for 6 hours and cold for 8 hours, according to the maker. A silicone sleeve adds grip, and a flip lid lets you open the drinking hole with one hand. That combination suits commutes and desk-side sipping, but the care requirements matter if you want a mug you can toss in the dishwasher. ## Best use cases This mug is aimed at coffee, tea, and other drinks you want to carry between home, the office, or the car. Picture opening the flip lid at a red light before setting off, then taking a sip through the drinking opening once parked, the lid is designed for one-handed access, though that does not make it a reason to drink while driving. The drinking hole can also be used with a small straw. It comes in 380ml (12oz) and 510ml (17oz) sizes, so you can choose between a more compact cup and a larger serving. The listing also names wine, juice, and oatmeal as possible contents. The wide mouth should make adding ice and reaching inside for cleaning easier than with a narrow opening. If your priority is an uncomplicated cup for use at home, an open mug may be easier to wash and use, this one puts more emphasis on taking a drink along. ## Product specs - Material: 304 stainless steel - Insulation: Double-wall vacuum design - Sizes: 380ml (12oz) and 510ml (17oz) - Lid: Flip lid with a silicone sealing ring and drinking hole - Grip and base: Silicone sleeve and anti-slip bottom - Care: Hand wash only, not dishwasher safe or microwave safe - BPA-free, according to the product description The silicone sleeve is intended to make the body easier to hold, and the anti-slip base is designed to help keep it from sliding or tipping. The mug is described as lightweight and compact, but no weight or dimensions are provided. Its lid is presented as leak-proof, still, if you carry a full mug loose in a bag, the listing does not explain how it performs in that situation. Would a simpler, dishwasher-safe cup be more convenient for your routine? That is the key trade-off here: portability features come with hand-wash care. ## Where it shines The useful details work together for everyday carrying rather than just looking like a travel cup. A car-cup-holder-friendly shape, a grippy sleeve, and a flip lid address common small annoyances when moving between the kitchen, car, and desk. The two size options also let you decide whether a smaller coffee or a larger drink fits your day better, without assuming that one capacity suits everyone. It’s a great fit if you want an insulated reusable mug for a commute or office routine and are comfortable washing it by hand. It may not suit you if dishwasher convenience or microwave use is essential, or if you need published dimensions to confirm a precise fit. Unlike a basic open cup, this design adds a lid and insulation for carrying drinks, in exchange, it asks for more care and the listing does not provide detailed leak-test conditions. ## Should you buy it? Choose this mug if the combination of vacuum insulation, a one-handed flip lid, and a silicone grip matches how you travel with coffee or tea. The 380ml and 510ml choices make the capacity decision straightforward, and the stated hot-and-cold holding times may appeal if you want a drink to last beyond the first few minutes. The main drawback is practical, not hidden: it must be hand-washed and cannot go in a microwave. If you want a low-maintenance cup for quick drinks at home, a simpler mug is likely a better match, if you want a portable, covered cup and accept hand washing, this design is more aligned with that routine. ## Images ![304 Stainless Steel Travel Mug — 1](https://www.ofertitastop.com/i/faTHyOx_U4wr2MjkvYaHJF2bDFM12oNQsvEWmticMkvxfKWyH4JXJQljamiKYrXRin1-MgMOB5v07AunYUBMlsQLZ8qp5VY96W9AQ6Vkr2ncZa8fpcd7hjsgTw.jpg) ![304 Stainless Steel Travel Mug — 2](https://www.ofertitastop.com/i/EMqgHmJISHgXTNg5zh5JvTA1OsWmZO1Bo2Zg7uwuC30dEWdlZer4QU890pjLURZJfgMzJcQp86TgmmQFckufVnWnwVPXTX55kd-d8yYaLipSGO-6KI0YoUi7hA.jpg) ![304 Stainless Steel Travel Mug — 3](https://www.ofertitastop.com/i/6wdHg2C_9gPwPq1dydQdwb3JqBS8waxv4RDf9JGpc1uKhG519AIuthnVpA9Nr2J5zBJlF_KSF3qpIPnag-CCyqbAr6ZCUMEy46eUlAyOM19o3Ib3U1UGpsgdSw.jpg) ![304 Stainless Steel Travel Mug — 4](https://www.ofertitastop.com/i/hktgYCs77sepxffph9voGvcmzR3XBHtJt-LQGYyomWHdCKE8Mzl2ywR-YfkXwqyfdCwHv3JY7FLj4PhClPbop_DPRX781e1KLv6JILrgoq8lXeBM5TTNQoHMKw.jpg) ![304 Stainless Steel Travel Mug — 5](https://www.ofertitastop.com/i/12Q6t6U7ct7KRwV-zVAtPPJZ12714atZpD71Woh3bSYi0PIFgyLHW-0yt45-uPpi_QCxrMgXhqHjJD9AGcFekWq6cwFqlrP9Otxw3IQE_GuprdGN9PnJRMfYzQ.jpg)
