Let customers speak for us
I bought this in replacement to my previous mug where I purchased 2020. It's been 5 yrs and the mug still in good shape and quality even if it has been fall several time. I tried to find the lid replacement but the model I had already phased out. Good thing there is a reseller here in Ireland so I dont need to buy abroad. The brand is reliable and the product is of good quality. The price is an investment. This I bought can be use for another years. If there will be another new design in the coming years, I would still buy and recommend the same brand. The only thing that I am looking is a mug bag holder that I can carry it in my shoulder. They have other style that has holder but they dont have a large capacity. I bought this since this is the only large capacity.
Термокружка Zojirushi Travel Mug SM-YAF48XA (480 мл) залишила дуже позитивне враження. Вона відмінно тримає тепло — напої залишаються гарячими багато годин, а холодні довго не нагріваються. Якість матеріалів на високому рівні, нічого не протікає, кришка зручна у використанні.
Дизайн стильний і лаконічний, зручно тримати в руці, добре підходить для щоденного використання, роботи чи подорожей. Також легко мити та доглядати. Однозначно рекомендую всім, хто шукає надійну та якісну термокружку.
The Zojirushi Travel Mug SM-YAF48XA (480 ml) is an excellent travel mug. It keeps drinks hot for many hours and cold beverages stay cool for a long time as well. The build quality is outstanding, it is completely leak-proof, and the lid is very easy to use.
The design is simple and elegant, comfortable to hold, and perfect for everyday use, work, or travel. It’s also easy to clean and maintain. I highly recommend this mug to anyone looking for a reliable and high-quality thermal mug.
Exactly what I wanted—feather-light, truly leakproof, and it keeps drinks hot for hours. Filled near-boiling at 05:00; by noon indoors it was still ~60–65 °C ☕🔥. The 480 ml size is a sweet spot and fits car cup holders; the one-touch lock feels backpack-safe. Only wish: fewer stickers on the cup (or gentler adhesive). Lime Green looks awesome. My daily carry mug—highly recommended! 😊
Im using my travel mug for about a week now. Coffee stays hot for hours. Hasn't leek. Drinking from it is very easy. Color is lovely too.
Great, its my second one in last 10years
Delivered.
Excellent flask. Very neat and really holds onto heat. Bought as a gift but will be buying one for myself.
