Review: SEARCH NO FURTHER - I bought 2 of these, a 20 oz for my daughter to take to Uni and a 30 oz for myself (currently OOS). I don't often leave reviews, as a lot things these days are mediocre at best and crap at worst. Not these 'beasts'!!! They are amazing! The seal fits really well and is easy to put back on if you remove it for cleaning, as I do. It keeps cold drinks cold for over 24 hours and hot drinks...I had a hot chocolate in mine and forgot it had been made. 4 hours later it was still piping hot, to the point I left the lid open for it to cool down!! The eco friendly straws and cleaning brush are a bonus, you don't often get them included with flasks/mugs (my partner calls then cups, I say he's wrong and they're flasks, but hey, potato potaato 🤷‍♀️ I have bought numerous other brands, both from desertcart and other places, in a long search for the perfect flask. And now I have found it. The old saying "buy it cheap, but it twice" is definitely true, as is "you get what you pay for". I actually don't mind paying more, for a product that genuinely does what it claims to do. And this product does. I have a kitchen cupboard full of plastic ones, metal ones, some leak, some are impossible to get clean, some can't go in the dishwasher, some are going rusty....I'm sure you get the picture. These Beast tumblers are worth every penny. I've spent less on others, which ultimately leak and I've spent more on one "dishwasher safe" one that is going rusty around the top now. If you are looking for a high quality flask, that can keep your drinks both piping hot and freezing cold (I'm intrigued about the icecream idea from another review 🤔) THEN THIS IS THE PRODUCT YOU NEED. What's more, there are so many different colours, with colour co-ordinated lids, the whole family can have their own with no confusion over whose is whose. Can't recommend these highly enough 👌
Review: Love my mug - Great size & quality. Love the colour. The lid doesn’t crack like my old one. It’s okay to hold but I’m definitely going to buy a larger one with a handle for ease and use this one for my coffee. The steel straw is narrower than my other ones which is good as I add lemon to my sparkling water drinks and worry about it eroding my teeth with wider steel straws. I’ve only knocked it over once but the lid stayed on and minimal water escaped through the sip hole. The paint hasn’t chipped like my old one. It keeps my cold drinks perfectly cold. My hot drinks hot. My only regret is not buying a bigger one with a handle. If you have smaller hands, I’d recommend a handle one.

## Questions & Answers

**Q: Can the sliding mechanism on the (30oz) lid be disassembled for washing? 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.

### ⭐⭐⭐⭐⭐ Fantastic Product - I Got What I Paid For!
*by M***S on 19 May 2023*

It is so rare to actually purchase something nowadays and genuinely get what you pay for! Or to put it in a better way, something of decent quality. As many cut corners or try to find ways to min-max profit, quality is rare (unless you pay exceptionally high prices for something), which not many of us can do and when you do get excellent quality for a reasonable price it's a lovely and rare feeling :) Pros: •Huge capacity 40oz (1136ml) Over a Litre •18/8 Food Grade Stainless Steel •Insulated Vacuum Layer •Hardwaring Slightly Textured Coating helps me grip. Great colours. •Decent quality Thick, Food and Heat Safe Plastic Lid, With clever leak proof seal and nice simple hinge. •Easy to clean, keeps an entire pot of coffee hot for at least 6 hours, keeps cold drinks cold (Ribena and Ice still had Ice in it all day). •Comes with Two Stainless Steel Straws and a Straw Cleaner. Nicely Packaged with a lifetime guarantee. •Simple, straightforward design, it works unlike other brands with smaller cups that I've tried which leak or break almost immediately. Cons: •Handle (Also cleverly designed and good quality moulding and material) sold separately but I can forgive this because of the exceptional quality and need to recoup material costs for production. To sum this up it inspired me to give it this glowing review which I rarely do, It's easy to maybe look at the price and think it seems a bit high but for less than thirty quid it really isn't, this simple design with quality materials IS NOT cheap to produce, they are making a profit but the price is fair and equivalent to a top end big brand, with I think better Quality and beats a cheap plasticy generic version with poorer materials hands down. Dont spend a fiver and dont spend fifty quid get this instead. Time will tell how well it lasts before the lid looses pressure or leaks or if it scratches, but I can tell for the quality it is, that even under my heavy use it should last for a fair and reasonable time, they do have a guarantee and I'll happily give Greens Steel more money for the next one even if its not under warranty. Buy One it's phenomenal! :)
