My milky tea gets inside and is starting to get crusty/flaky...** A: I have the older version of the lid too. It usually comes out clean if you put it through the dishwasher but needs a good shake afterwards. You can also try holding it sideways under warm running water for a min and then vigorously shake it over the sink. Try the other side and repeat. Do this with the lid closed and opened. **Q: Is there a way to keep the straw from rattling around? I use it in a quiet office and it so noisy.** A: You can get silicone bumpers that slide onto the straw on either side of the lid, to hold the straw in place and keep it quiet. Some products even come with tips as well as bumpers, in case you don’t care for the metal straw hitting your teeth. Amazon sells them. I have had zero rattling since I started using them, and I enjoy the tips, no burning your lips on a hot straw. **Q: Just got mine in and I love it. I can tell I’ll need more straws so what size should I get? I like the wide straight one. What size is it?** A: I have a 40oz Beast which I love. I use the metal extra long straws, however, the regular size metal straws can work. **Q: Can u use this cup without the straw** A: Mine has no vent which makes it difficult to get much liquid out. I’m considering returning it as I don’t like drinking out of a straw. ## Customer Reviews ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars BEAST! *by D***O on Reviewed in the United States on October 25, 2024* This is the best insulated tumbler I have ever owed. The fit and finish are awesome, it is spill proof like they claim and the 20 oz fits in the cup holder in my car! They come in a ton of colors, ice stays cold for hours! I liked the tumbler so much I bought another one as a gift. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Great value *by J***L on Reviewed in the United States on November 26, 2024* Durable. Keeps water cold for hours. Haven't tested with hot beverages. Impressed with the brand. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars It’s a chonker but really does the job *by J***N on Reviewed in the United States on June 8, 2024* We are moving away from all things plastic in our lives. That includes travel cups. I loved my tall Starbucks cup but wanted something that wasn’t polycarbonate and would keep things cold for longer. I also have arthritic hands now, so need the security of a loop or handle for holding on while I walk. This fills the bill. It’s a chonker! A bit chubby for any kind of mesh pocket on a backpack or bag, but I bought the slip-on handle to go with it and that makes it easy to carry. Without the handle, I’d be struggling with this for sure. It does fit in the cup holder in my Xterra, so good for driving as well.I can fill it with ice, add water, continue to add water as I drink up what’s in the cup, and I’ll still have ice 12 hours later. In fact, I left it on the table overnight just to test and found ice in the cup 24 hours later - not a lot, but the water was still cool to taste.It keeps my drinks nice and cold but doesn’t sweat on the outside at all. I can’t attest to hot drinks because I don’t drink hot beverages, but it sure keeps cold drinks icy on relatively little ice. That’s the other thing I like - I don’t have to pack it full of ice in order to keep my drink cold. I can use less ice than I normally would which means more beverage for sipping with each fill. That’s really great when traveling as I like to order brewed iced tea from restaurants and put it in my to go cup (trying to avoid plastic bottles).The top is snap on - a nice tight snap on - and made of polycarbonate. There’s a rubber seal attached to the lid that holds tight to the inside of the cup. The flip-up part for drinking has a hole large enough for straws or for getting a good amount to sip. The straws (one bent, one straight) are stainless and come with a cleaning brush. I’m not a fan of straws, so those will sit in a drawer for occasional use. I did test the seal by filling the mug and turning it upside down. Not a drop spilled out with the sipper flap closed. You could have spills with it open, even with a straw as there’s no gusseted opening for the straw. That’s really the only downside. All in all, this was a great purchase that I’m really happy with.Overall, I like the cup. It’s not heavy but is well-insulated and keeps my drinks nice and cold for hours. I chose the aquamarine and really like the color. ## Frequently Bought Together - Beast 40 oz Tumbler Stainless Steel Vacuum Insulated Coffee Ice Cup Double Wall Travel Flask (Purple) - Greens Steel Handle for 40 oz BEAST Tumbler Only | BEAST Tumbler Handle Anti Slip Travel Mug Grip | Beast Cup Holder | BEAST Tumbler Accessories | Lightweight Tumbler Holder | Cup Handle --- ## 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.vn/products/240089919-beast-40-oz-tumbler-stainless-steel-vacuum-insulated-coffee-ice](https://www.desertcart.vn/products/240089919-beast-40-oz-tumbler-stainless-steel-vacuum-insulated-coffee-ice) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-15*
