Specifically, it would have been very easy to put threads on the cup rims to allow them to securely screw into the bottle. Instead, they are held on by friction applied to rubber gaskets on the bottle. This means that the cups easily slide off the bottle. The cups are also shaped such that a large amount of the object’s volume is unused space in the cups. They could have been shaped such that the cup’s interiors were filled by thermos space, increasing the volume of the vessel. The bottle is symmetrical on the up/down axis (mine has no logo), meaning you have a 50% chance of removing the cup on the bottom every time you open it, having to replace it and remove the other to pour out your drink. Finally, the lid that holds the beverage inside the bottle is plastic, when it easily could be made of metal, meaning that the whole time it’s closed boiling water is in contact with plastic, leaching whatever’s in the plastic into the beverage. I’ll be keeping it because the faults aren’t problematic enough (yet) for me to decide to return it, but the designers should take notice and fix these careless flaws. ### ⭐⭐⭐⭐⭐ Proofed its value in Canadian cold. *by G***. on Reviewed in the United States on January 1, 2019* Very good quality thermos. I took it to our trip to Canada on Christmas and it had proofed it's value. We were walking outside in 8°F basically the whole day, and at the end of the day we got our tea still hot. I was surprised, but it really holds the temperature for a whole day long. It's also nice that it comes with 2 separate cups (1 on the bottom and 1 on top) so that each of us have had our own cup.Exterior surface is kind of glossy, so it feels looks expensive. I think it would be a great gift, at least for an outdoor enthusiast. ### ⭐⭐⭐⭐⭐ What a fun way to stay connected with friends! *by M***H on Reviewed in the United States on January 18, 2019* I LOVE this! Last summer when my husband and I went to the beach we dragged along a water bottle full of wine and plastic party cups. Needless to say, enjoying warm white wine wasn't super great. Now, we can enjoy our wine cold and don't need to bring those awful party cups. This is our all in one beach solution for our beverages now. Now that's it's winter we also like to bring it up on the slopes for hot chocolate breaks! I also love the sleek design! --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/86274320-duett-stainless-steel-double-walled-vacuum-insulated-reusable-3in1-travel](https://www.desertcart.vu/products/86274320-duett-stainless-steel-double-walled-vacuum-insulated-reusable-3in1-travel) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-08*
