A number of colourways including rose petal, orange cream, and sea glass aura have already sold out with shoppers snapping up this Amazon deal.

But at the time of writing you can still get the shimmery purple design, with Amazon saying the 'deal is selling fast'.

It's the Periwinkle Shimmer design, which is usually priced at €57.72 and has been slashed to €34.62 for a limited time.

The viral tumbler became a must-have for a reason, with people praising its lost-lasting temperature control and durable design.

The tumbler uses vacuum insulation to keep drinks cold for up to 11 hours or up to two days when filled with ice, making it ideal for commutes, workouts, long days out, road trips or staying hydrated on-the-go.

Made from 90% recycled stainless steel, the Stanley Quencher is designed with sustainability in mind, offering a sturdy, reusable alternative to single-use bottles.

While a standout feature is the FlowState screw-on lid, which gives you multiple ways to drink, whether you prefer using the straw for hands-free sipping or switching to the open spout.

More than 10,000 shoppers have tried and tested the Stanley cup, giving it an average rating of 4.5 stars on Amazon.

One customer said in their five star review: "Wow wow wow where do I start. I brought this for my self as I was going on holiday and thought this would be useful to keep my drinks cool and for the price I would’ve hoped it would work.

"But it blew away my expectations. It worked perfectly. I would fill it up in the morning then 10 hours later in 35 degree heat it would still be ice cold. Plus, it doesn’t leak and really durable unlike other bottles."

Another wrote: "It's sturdy, easy to clean, I love that its dishwasher friendly and best of all it keeps drinks either hot or cold for hours. It's easy to carry and there's no after taste when drinking your desired drink.

"It's a good-quality cup that does its job really well. Worth it if you want something durable and stylish."

While a third said: "Great product overall, I’m carrying this bottle wherever I go. It is true that holds temperature for hours and hours, great for going to a hot weather and wants to keep your drink cold.

"Easy to wash as well. I bought the big bottle which can be heavy when full of liquid, keep that in mind."

Others said "I wish I bought this sooner, I use it all the time" and "absolutely lives up to the claims".
