Moreover, it serves brilliantly as an on-the-go cup for warmer fare, such as mulled wine, tea, or soup, keeping them hot for approximately 45 minutes. Yet Brits looking for a traditional pub pint might need to adjust their expectations slightly when considering this cup, reports the Mirror.

Due to the use of the American pint measurement in its moniker (equal to 470ml, versus the British pint glass capacity of 568ml), it may not hold a full UK pint. Notwithstanding, the stackable nature of the cup has earned it accolades from consumers on Amazon for both its functionality and style.

A contented customer said: "It does the job perfect! We bought for an overseas all-inclusive holiday in order to keep our drinks cold for longer. They certainly kept our drinks cold in the 39C heat for quite a while! The envy of other guests as well as the bar staff!".

Another customer shared their experience and said: "I purchased two of these cups (white and blue) to take on holiday with me, so I wouldn't have to drink out of the small plastic cups most hotels have during the day time to serve drinks and the beach/pool."

They went on to say: "I used them every day for two weeks, and we found our drinks consistently kept ice cold, to the point where ice in the drinks simply wouldn't melt for hours, or slushy drinks remained the same consistency."

Another individual commented: "I'm not sure how it does it, but it does keep your beer cold even when directly in the sun." A different review stated: "I was curious how long tea would stay hot in a open ended flask. Surprisingly it keeps hot to warm for about 40 minutes. Also, it's bigger than your standard mug so you can make one big cup of tea that stays hotter for longer."

However, not all feedback was positive. One disgruntled user claimed: "This is marketed as a product intended to keep your pint cool. It certainly foes that but at the same time the metallic interior has ruined the taste of every beer I have tried it with." Another dissatisfied customer remarked: "Awful quality. The bottom came out just 32 days after purchase - and that was being washed by hand. I can only imagine if you put it in the dishwasher!".

For those looking for other options, there are numerous alternatives to these cups on the market. For instance, Ninja's Thirsti 530ml Travel Bottle is available for £29.99 directly from the Ninja website, while the YETI Rambler Stackable Cup, which holds 20oz (591ml), comes in various colours starting at £25.
