LG 55UJ701V reviewLG 55UJ701V review
The LG 55UJ701V offers compelling value for money. A 55" HDR TV with premium looks for around 850 has to be worth considering, and the UJ701V is well featured too, with Freeview Play, Freesat compatibility and comprehensive Smart TV, including Netflix and Amazon. Viewing angles are particularly wide, making this a good choice for a family TV.

Samsung Galaxy J5 2017 reviewSamsung Galaxy J5 2017 review
The ever-popular Samsung Galaxy J5 has been upgraded for 2017 with a full metal body, and a fingerprint sensor embedded in the home button. It's a smart, slim phone with a good-sized 5.2 inch AMOLED screen and fast performance from its 8-core Exynos processor. The new 13 megapixel front camera will be welcomed by selfie fans, and battery life remains strong. It's a good all-rounder, but we'd like to see the price fall.

Sony Xperia XA1 reviewSony Xperia XA1 review
The Sony Xperia XA1 is a mid-range phone with premium styling. It's superslim and very narrow, with almost no bezels left or right of the screen. Equipped with 32GB of storage and a fast 8-core processor, it's not lacking in any department. But perhaps its top feature is its class-leading 23 megapixel camera.

Samsung UE55MU6100 reviewSamsung UE55MU6100 review
The Samsung 55MU6100 gives you a big screen for little money - around 750 or less, which is extremely good value for a 55-inch TV. The MU6100 may be a budget TV, but it's a 4K model, HDR-compatible, with superb Smart TV. Watch out for the slow 50Hz refresh rate when watching sport, but otherwise consider this to be one of the great bargains of 2017.

LG OLED55B7V reviewLG OLED55B7V review
The LG OLED55B7V is an outstanding buy. OLED display technology gives you the best possible picture quality, and the B7 is the most affordable OLED TV in LG's 2017 range. It's super-stylish too too, with its blade-thin screen. It has superior audio and excellent Smart TV. The only issue is the price, but we expect this to fall.

Sony Xperia XZ Premium reviewSony Xperia XZ Premium review
The Sony Xperia XZ Premium is a premium-spec version of the XZ, with a 4K HDR screen, a next-gen processor, enhanced camera, more memory and a bigger battery. It's a beauty for sure, and not over-priced, but may be too big for some users.
