The Thirsti stands alongside other premium competitors such as Yetiand Stanley, whose Rambler andQuencher flaskshave garnered celebrity and influencer endorsement. Ninja's offering boasts the sophisticated technology expected from the manufacturer and, following its launch last year, savvy shoppers made it a Black Friday bestseller on Ninja's website as well as an Amazon chart-topper during Prime Day, reports Nottinghamshire Live.

Ninja claims that throughout trials, the BPA-free travel flask maintained beverages chilled for up to 24 hours or heated for as long as eight hours, courtesy of triple-wall Thermo insulation encasing. Customers on Ninja's website have awarded the product an average rating of 4.6 stars out of five across 531 buyer reviews, with 92% of purchasers stating they would recommend the item.

One buyer hailed the Thirsti as 'the best bottle I've ever owned,' as they said: "I've been buying other brands of thermal bottles for many years and, although the Ninja one is priced around the same as the others, it is far superior in keeping drinks cold.

"It literally keeps ice cubes in ice form all day, and it looks cool. I'm about to order another two for gifts." Another five-star assessment rated the 'brilliant' flask as 'better than a Stanley'.

As they said: "Very impressed with this drinks bottle and would not go to anything different." The buyer wasn't the only one claiming the flask beat the renowned Stanley.

Another said: "I put fizzy pop and some ice cubes into my cup when I started work at 6pm, by 8am when I finished, it was still icy cold, still as fizzy as when it was freshly opened, and still had the odd trace of ice cube floating around. I am really impressed.

"The bottle itself looks modern and slick, and, as a mobility aid user, the wrist strap makes it so much easier for me to carry around. Cheaper than its leading competitor (who should stick to making tools), the Thirsti is a must for keeping cool on the go."

Whilst numerous shoppers have praised how robust the Thirsti is, it actually proved too weighty for some, with one three-star review noting: "The cup is ok, but when fluid is put in it's very heavy, gifted it to my husband."

Another issued a caution for those eyeing the lighter colours: "Lovely bottle, keeps my drinks very hot. However, it marked very easily and now looks very old. I wish I'd bought the darker colour bottle."

Generally customers have been delighted with the Thirsti's capacity to keep drinks cold, with one reviewer declaring it 'the best drinks bottle you can buy' due to its remarkable insulation. They explained: "I like to fill it up at nighttime with a Slushie and take it up to bed with me as it is still frozen and slushy the next morning. If I do that with another drinks bottle that I have it turns to water by the morning."
