As the cold winter months continue, taking a hot drink out with you may help get you through the commute, a long walk or a long car journey, whether you want a caffeine boost on the go or to warm up.

While a thermal flask may do the job for a hot drink, the Ninja Thirsti works for all different drinks, as it keeps cold drinks cold for up to 24 hours, hot drinks hot for up to eight hours, and retains ice for up to two days. Plus, the unique design also stops fizzy drinks from going flat.

The bottle proved hugely popular with shoppers in 2024, but one of the biggest discounts we've seen on the bottle is happening right now. While it's reduced to £19.99 from £29.99 on Ninja's website, on Ninja's official eBay store, you can get the 530ml bottle for just £17.99. 

The bottles on the eBay store are brand new, and after using the discount code FRESHFINDS, makes it the cheapest place to get one, rivalling Amazon too. The black and blue shades are still available - but almost 1000 have been sold in the past 24 hours, so you'll have to be quick.

The 700ml version is also discounted on eBay, and while it's not quite as popular as the smaller 530ml size, it could be useful for a family to share on a day out, or if you're trying to hit your water intake and keep it cold. At full price, the 700ml Ninja Thirsti costs £34.99, however with the discount and coupon code you can buy it for £22.49 on eBay.

The bottles have received mostly positive feedback on eBay, with one review saying: ''Flask is such good quality there doesn’t seem to be anything it can’t do… keeps contents hot or cold, still or fizzy for long periods of time. It’s magic [I] would definitely recommend.'' [SIC]

A second shopper commented: ''Size is good, supports hot, cold drinks and even fizzy drinks which is nice! Overall this product is good quality and is competitive to the Chilly's brand.''

However, not all shoppers were as praising of the bottle, as one added: ''Advertised as keeping hot drinks hot for eight hours or more, my drink was almost cold after eight hours.''

The Thermulate Insulated bottle from Regatta is reduced to just £10, and comes in black or sage shades.

The Thermos Stainless King Travel Tumbler is £19.50 and keeps the contents hot for 7 hours or cold for 18 - available at Amazon.
