Samsung UE50NU7400 reviewSamsung UE50NU7400 review
The Samsung UE50NU7400 is a bargain hunter's dream. You'll be hard-pressed to find another TV that gives so much for so little. We love the 50-inch screen, UHD HDR support, access to streaming content, smart looks and user-friendly interface. Ideal for anyone on a tight budget.

LG 55SK8500PLA reviewLG 55SK8500PLA review
The LG 55SK8500PLA is our top pick of LG's LED TV range for 2018. Picture quality is superb, with LG's Alpha 7 processor and local dimming technology delivering smooth motion and bright, vivid colours. With support for the latest HDR standards, plus Google Home and Alexa support, its future-proof too. Audio quality is very good, and the price is reasonable.

Apple iPhone 8 Plus reviewApple iPhone 8 Plus review
The Apple iPhone 8+ is a larger version of the iPhone 8. With a bigger screen and a superior camera, it's the best iPhone of the current generation, but also the most expensive. Compared with the 7+, the 8+ offers more memory, a faster chip and wireless charging.

Apple iPhone 8 reviewApple iPhone 8 review
The iPhone 8 has a new glass design offering wireless charging. It's faster than ever, thanks to the new A11 Bionic chip, and now comes with 64GB of memory as standard. iOS 11 also brings some cool new features including augmented reality. But as ever, the price of owning the latest iPhone is higher than ever before.

Samsung Galaxy Note 8 reviewSamsung Galaxy Note 8 review
The Samsung Galaxy Note 8 is an enhanced version of the S8+. Even thicker and heavier, it's a massive phone and won't be suitable for everyone. But it offers the same incredible curved AMOLED display and top-end specs as the S8+, plus an S Pen, dual lens camera, iris scanner and 6GB of RAM, making it the most powerful phone ever.

HTC U11 reviewHTC U11 review
The U11 is HTC's flagship phone for 2017. Top features include the Quad HD display, 8-core processor, 64GB of ROM, and the impressive camera. It's water resistant too, and comes with a unique squeeze function. But the U11 costs more than the Galaxy S8 and iPhone 7, and we don't see why it should.

Motorola Moto C reviewMotorola Moto C review
The Motorola Moto C is one of the cheapest smartphones you can buy, and if you're looking to spend under 100, then this is as good a choice as any. Don't expect it to be anything more than a very basic phone, and you won't be disappointed.
