Samsung Galaxy Note7 reviewSamsung Galaxy Note7 review
The Samsung Galaxy Note7 is built on the same platform as the S7 Edge, sharing its stunning curved-glass design, with a huge AMOLED Quad HD screen, 8-core processor, outstanding camera, and a huge amount of memory. In addition it adds S-pen functionality, making it a superb productivity tool. But the sky-high price and problems with the battery can't be over-looked.

Apple iPhone 7 Plus reviewApple iPhone 7 Plus review
The Apple iPhone 7 Plus is the best iPhone, with a better screen than the iPhone 7, a new telephoto camera, stronger battery life, faster processor and more memory. But it's a big beast - too big for some - and the price has risen yet again.

Sony Xperia X Compact reviewSony Xperia X Compact review
The Sony Xperia X Compact is a high-end compact smartphone with a fast processor, outstanding camera and plenty of memory. Lightweight and easily pocketable, it offers most of the features of Sony's flagship devices. However there are a few compromises and it seems over-priced compared with the alternatives.

Apple iPhone 7 reviewApple iPhone 7 review
The Apple iPhone 7 keeps the same look as the previous model, but is now water-resistant and comes in a Jet Black colour option. The iPhone 7 is faster, with more memory, a better camera and longer battery life, but the price has gone up again. Oh, and the headphone jack has been removed.

Microsoft Xbox One S reviewMicrosoft Xbox One S review
The Microsoft Xbox One S is a very welcome upgrade to Microsoft's game console and all-round entertainment system. 40% smaller, and with an internal power supply, it's a much nicer-looking box. It's also a low-cost way to embrace UHD Blu-ray, and brings 4K streaming, plus 4K upscaling and HDR support for games.

Sony Xperia E5 reviewSony Xperia E5 review
The Sony Xperia E5 is a decent mid-range smartphone, with an attractive slimline design. Priced in the competitive mid-range, it's not lacking in any way, but neither does it particularly stand out. We reckon it's a safe choice that won't let you down, but it's worth shopping around and looking at similarly-priced rivals.

Samsung Galaxy J5 (2016) reviewSamsung Galaxy J5 (2016) review
The Samsung Galaxy J5 (2016 Edition) is a mid-range smartphone with premium design and a good spread of features. We draw your attention to its superb AMOLED HD screen, exceptional battery life, Android Marshmallow, 16GB of memory and 2GB of RAM. The Snapdragon 410 processor isn't the fastest in town, but it gets the job done.

LG 55UH950V reviewLG 55UH950V review
The LG UH950V is LG's premier LED TV for 2016, and the 55-inch model is the best value. With its ultrathin screen and metal frame and stand, it's a real beauty. Picture quality is amazing, with rich colours, deep blacks and smooth motion. Audio quality is good too, with a 2.2 speaker system. Smart TV functions include the BBC iPlayer, Netflix and Amazon. Overall, it's a top TV, but be sure to shop around for value.
