I'm a massive fan of the Stanley Quencher cup, and they've just fixed its one major flaw
The brand has now launched a leakproof version.
The Stanley cup almost needs no introduction, but if you were unaware, here's what you need to know. It's a huge 1.2L tumbler complete with a built in straw and handle so you can stay hydrated while working from home or on the go.

The Iceflow™ Fast Flow Bottle 0.6L
Thanks to TikTok, it has achieved viral success with over 5 billion video views, as users rave about how it has upped their water intake. Due to its aesthetic variety of colours, it has also become somewhat of a status symbol in the water bottle department.
Since it first launched in the UK in 2024, the cup has been released in various new shades, which sell out extremely quickly (usually within 24 hours). Better yet, Stanley has just fixed the original Quencher's one and only flaw, creating a new leakproof Quencher Protour Flip Straw Tumbler for £50, which is available in five colours; Black Fade, Frost Fade, Rose Quartz Fade, Ash Fade and Azure Fade.

This is the latest launch from Stanley and features a flip straw design to make it leakproof. It comes in five colours and costs £5 more than the original Quencher bottle I've been using.
Priced at a whopping £44.99, I was outraged when I first heard the price of the bottle, how on earth can a refillable water bottle cost that much? Plus, with a capacity of 1.2 litres, how is anyone lugging it around with them?
So, I got my hands on a Stanley Cup and have now spent months using it daily to see if it really is worth the money.
When I say I've thoroughly tested it, I'm not exaggerating. I take it to the gym, on walks, in the car and even on holiday, where it spent hours by the pool and on the beach.
💸 Reasons to buy
Firstly, hand on heart, I've never been so hydrated in my life. I refill my Stanley on average twice a day, meaning I'm drinking almost 2.5 litres a day.
I love ice cold water, so every morning I fill it up with ice cubes and water. It stays cold for hours and hours on end, and 24 hours later (I tested this) the ice is still solid. It's like magic - I love it.
When I went on holiday in September last year, I filled it to the brim and brought it with me for the plane, car journeys and taxi rides - I get very carsick and found this was a lifesaver at keeping me free from the dreaded waves of nausea. Knowing I always had chilled water near me at all times did the trick.

Don't get me wrong, it's enormous, but after a week of using it every day, I got used to it and now it doesn't seem so big. Plus, it's unmissable so you'll never forget it.
The handle is also, excuse the pun, very handy, especially when walking to the gym or wearing a small cross body bag that it won't fit into.
Speaking of the gym, the lower third of the tumbler is in fact very slim, meaning it slots nicely into every cup holder I came across, whether that was on the treadmill, or in a car.
✋ Reasons to avoid
While the bottle has a ton of pros, it wasn't all smooth sailing.
Unfortunately, the Stanley Quencher H2.0 Flowstate™ Tumble isn't entirely leakproof, so it needs to be upright at all times. This is because there's no closure, even if you remove the straw and twist the rotating cover to seal the hole the straw goes through.
This doesn't make it unusable, just inconvenient if you want to put it in a bag. As someone without a car, who lives in London and gets the tube a lot, I feel I can't bring it with me unless I'm prepared to hold it separately - if I have a day of meetings or an evening event to go to, I usually leave it behind.
However, Stanley has just launched a leakproof version with the Quencher Protour Flip Straw Tumbler. Costing £5 more than the one I have, it will set you back £50, and features a features a flip straw lid that means it can be securely closed when not in use.
