I bought it January 2023 and it’s January 2026 now. I got a Stanley for my birthday as a gift so I compared the two. My $30 dollar rainbow beast to the $50 Stanley glitter bomb. The quality is absolutely amazing on both cups my drink is cold and still has ice after 14 hours I haven’t tested for hot in my 40oz but I have the 20 and it keeps my coffee hot through lunch. I love the design and colors offered on beast the rainbow is my favorite. The beast tumbler is lighter than the Stanley and I prefer the removable cuff handle that I have for the beast tumbler. Car cup holder though the Stanley was a better fit but it’s really tall. My beast fits in the cupholder if I had the coaster in the bottom of the cup holder so eh not a big deal. The one thing I like the Stanley over the beast is the lid. The beast has an opening so that you can use it with or without a straw so bugs can get in hair/dust while the Stanley is closed top 100%. I love both cups but for quality and bang for your buck beast is the winner. Review: HOT, COLD, AWESOME! - These cups are awesome!! I love the colors, and I love the way they keep drinks hot and/or cold! We have seven of them in different colors, and we have had our original two for nearly 5 years. They are very large for a woman's hands, so the handle that is sold separately is definitely recommended. They offer a 30-ounce size, which is much easier for women to hold. They are steel, so they don't rust, and the colors are made with a vinyl covering. We have found these cups to do an excellent job at holding the temperature of any drink you put in them, and they will keep cold drinks cold even when left in a hot car for hours. Each cup comes with metal straws in two sizes and a brush for cleaning inside the straws. We wash them in the top rack of the dishwasher and have had excellent luck with that. These cups are strongly recommended. ## Features - #1 INSULATION & TEMPERATURE RETENTION - Over engineered and tested against leading brands.

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 ### ⭐⭐⭐⭐⭐ Beast vs. Stanley *by C***S on February 28, 2026* I can’t say enough about this cup.
