Ninja has been one of the first brands to launch their Boxing Day sales for 2024, offering price cuts on a range of products from air fryers to knife blocks. Many of the deals on the site are either cheaper than those seen on Black Friday, such as this offer on the Ninja kettle which brings it down to its lowest ever price, or come with complimentary items and bonuses.

However, shoppers eager to secure one of Ninja’s latest bestsellers have discovered a method to combine deals and purchase it for even less than the sale price. The Ninja Sip Perfect Travel Mug, which only launched in the UK this month, has already garnered a loyal following among coffee and tea enthusiasts, with many hailing it as the ‘perfect’ insulated cup.

The mug is available in a selection of chic colours including black, white and green. It was initially priced at £29.99 and the Boxing Day sale sees it discounted by a third to £19.99, a substantial saving for anyone keen to get their hands on this game-changing gadget.

However, astute shoppers have identified a way to acquire it for even less via a money-saving site. Bargain seekers who register with TopCashback in time for the Boxing Day sales can secure the mug for £3.66 by signing up as a new member, claiming a free £15 signup bonus and cashback, and then proceeding to purchase the travel mug.

As one would anticipate from the pioneering brand that has revolutionised British households with innovative devices integrating cutting-edge technology into products ranging from air fryers to barbecues, this travel mug is far from ordinary. Beyond its leak-proof lock, it boasts a novel HeatStore technology that rapidly cools beverages to the ideal sipping temperature in mere minutes and maintains it for hours on end, reports Wales Online.

Although it has only been on the market for a few weeks, the Sip Perfect has garnered an impressive average rating of 4.7 out of 5 stars on Ninja’s official website. Customers have lauded its exceptional quality and value for money.

One satisfied customer hailed it as “top class”, albeit noting its slight heaviness, and elaborated: “I had high expectations of this product as Ninja has a reputation for quality and I’m pleased to say it didn’t disappoint. As an outreach worker a good thermal cup is an important part of my ‘kit’ I decided to use this mug for a few days before writing the review to make sure I had put it through its paces.

“It looks great and has the quality finish you expect from Ninja. It didn’t leak even when in the bottom of my bag. I followed the instructions about preheating the cup and I think my filter coffee was hotter than when I poured it from the pot. It stayed hot for several hours which is brilliant when you are away from access to drink making facilities. I used the cup while working from home and again it kept my drink hot for hours.”

One customer was pleased with the cup’s design and durability, stating: “It’s easy to clean, looks great and has a tough external shell. It fitted nicely into the cup holder on my car. The only slightly negative thing I would have to say about this cup is, it’s a bit heavy but worth dealing with that as the product is a good one. I’m very impressed.”

Another shopper, particularly appreciative of its convenience for parents, described it as ‘great for mums on the go,’ and elaborated: “This is perfect. As a new mum with a newborn baby I use this to keep my tea, hot chocolate and cappuccino nice and hot. I take this out with me whilst travelling and I love it! The only thing I would suggest is that they could add handles to the cup as well.”

A third customer commended the cup for being dishwasher safe, saying: “The cup is stylish and keeps drinks hot for quite a number of hours. It washes well both in the dishwasher and by hand and it is easy to separate the different parts. The cup doesn’t fit in my car’s central cup holders but fits in the door. The cup doesn’t leak but I would have preferred a lid that closes automatically once you stop pressing on it because I have forgotten to close it a few times, this is user error.”

Despite the positive feedback, not all reviews were glowing, with the most critical review still awarding three stars. This less satisfied customer compared the mug unfavourably to another product from the same brand, remarking: “Doesnt keep drinks hot for long. I have the flask and that keeps hot drinks hot all day so I thought the travel mug would be the same. I should have just stuck to the flask. Not worth buying.”

For those with a penchant for coffee, the quest for the ideal travel mug is akin to a search for the Holy Grail. If this deal – which reduces the price of the Ninja mug to less than many takeaway lattes – doesn’t tickle your fancy, there are numerous other fantastic options currently discounted in various winter sales.

Coffee enthusiasts looking for an alternative high-end mug can bag a whopping 26% off the Contigo Luxe on Amazon at present. Usually priced at £39, it’s now down to just £28.99. Also on Amazon, Dualit offers a striking brushed stainless steel option, now reduced to £19.99.

Stanley’s renowned Aerolight is the hot beverage counterpart of the Quencher and is slightly cheaper than the celebrity-favoured cold drink cup. Available in eleven colours with prices starting from £33 on the Stanley website, if you’re content with specific colours, you can grab one from £30.
