Ninja Thirsti water bottle drops to cheapest price this year for Amazon Prime Day

The Ninja Thirsti Water Bottle and Flask has been reduced as part of a limited time Amazon Prime Day deal

Shoppers are saying they ‘will never buy another water bottle’ again since getting their hands on the Ninja Thirsti Water Bottle and Flask – and for a limited time it is 37% off. The brand’s bestselling water bottle is now £21.99 down from £34.99 for Amazon Prime Day, beating the Ninja website and Currys, where it is full price.

According to price checking site CamelCamelCamel, this is the cheapest the water bottle has been this year, and there are six different colours to choose from including mint green, black, white and grey. Shoppers will have to be a member of Amazon Prime to nab the deal, but they can sign up for a free 30 day trial here and take advantage of all the benefits.

The Ninja Thirsti leak-proof travel bottle is designed to hold any drink but a feature that sets it apart from other vessels is a clever smooth interior retaining bubbles for lasting fizzy beverages. It also claims to keep cold drinks fizzy and chilled for up to 24 hours, hot for up to 12 hours and iced for up to two whole days.

One customer highlighted the fizz feature as working by leaving feedback: “This is my 2nd flask I purchased this one for my husband. When we were away on holiday I put the unfinished bottle of Prosecco in my flask and the following day it was still cold and fizzy. Result.”

Another shopper kept their families drinks cold on holiday, writing: “This is perfect for using in hot countries it keeps the ice solid for 12hours plus making the water so lovely to drink all day. Used daily whilst in Kos when on trips or by the pool.” The 700ml bottle is on sale for £21.99, however a smaller 530ml can also be snapped up for less than £20, now on sale for £19.99 down from £29.99 for Prime.

Stanley also stock a number of travel water bottles, such as the Iceflow Bottle. It is more expensive at £40, but there is a wider colour choice, as well as fun patterns such as Rose Petal Motion and Cream Rose Gold. Shoppers can also get a 600ml version in a block colour for £30 as part of the Stanley summer sale.

Ocean Bottle is another option with the 750ml bottle retailing for £40. Again, it’s more expensive than the Amazon Prime Day Ninja Thirsti deal, but it does hold slightly more liquid, plus it can be personalised making it a great gift. It also has sustainability credentials with one bottle stopping 1000 plastic bottles from entering the ocean.

The Ninja Thirsti has been rated 4.6 out of five by 1,885 Amazon customers, many that applaud the bottle for keeping drinks hot or cold, fizzy and being 100% leak-proof. It’s also easy to clean in the dishwasher and ideal for travel as it is nice to hold, or can slot into the cup holder of most cars.

One happy customer wrote that it is a versatile choice, commenting: “This is designed for fizzy drinks, however it is excellent for the still water that I use it for. Keeps drinks cold all day, brilliant for the recent periods of hot weather. I use mine for all day walks and playing golf on a hot day. Highly recommended, far better than any other drinks bottle I have used in the past. The other good thing is that the complete top part of the bottle unscrews making it easy to fill and clean. It then has a simple small screw lid for drinking or pouring. It is quite heavy when full, but then it does hold a lot.”

They did point out that it can be heavy when full, another negative that someone else also mentioned. This shopper said: “One star off because they’re substantial and a bit on the weighty side.”

But, this hasn’t put off a five star reviewer, sharing: “I absolutely love my Ninja Thirsti – gorgeous mint green – perfect for iced tea and totally leak-proof. Keeps drinks cold all day, even without ice! Colour is beautiful and even better in person! It keeps drinks cold for hours; I add ice cubes in the morning, and they’re still solid after 8 hours. It also works brilliantly with hot drinks. It’s completely leak-proof, even when tipped upside down in my bag, and the quality is excellent. I’ve dropped it multiple times and it still looks brand new. This is a well-made, reliable bottle that’s totally worth the money. Highly recommend.”

Someone else explained: “What really sets it apart is how easy it is to clean and the thoughtful design of the mouthpiece – no leaks, no fuss, just smooth sipping every time. It also pairs perfectly with the Ninja Thirsti system for flavouring and carbonation (if you’re into that like I am).”

Shoppers can get the Ninja Thirsti from £19.99 from Amazon, however, the deal won’t stick around for long. The Ninja Thirsti System is coming soon to the UK, but in the meantime Soda Stream’s Sparkling Water Machine is half price for Prime Day, now £69.99 down from £139.99.
