Gigaset QV Series

60% The Gigaset QV830 is a cheap Android tablet with slow performance and a low-resolution screen

The display’s black levels were surprising, however. At 0.29cd/m2 the Gigaset QV380’s black levels were fractionally deeper than more expensive tablets such as the Tesco Hudl2, which is impressive. Its contrast ratio was also excellent all things considered at 1,031:1, as good as the Tesco Hudl2 and almost equalling the Asus MeMO Pad 8, both pricier tablets. Colours produced were suitably vibrant and, while not the most accurate, the display would have been respectable were it not for the low resolution and grainy texture.

Overall the Gigaset QV830 is a nice piece of kit with video delivery being superior to audio output. Included in the box is a standard-to-micro USB lead for charging and connecting to a computer. Connectivity to Wi-Fi networks is good as is its Bluetooth functionality. Additional storage is available via a micro DSD card or use USB OTG.

80% Gigaset QV830 review: A sterling budget Android tablet
Source: IT Pro Portal EN→zh-CN Archive.org version
The Gigaset QV830 isn’t perfect - it’s not an iPad mini or Kindle Fire HDX rival - but that doesn’t matter. Gigaset isn’t trying to compete with those models. The QV830 is a £70 tablet at the moment - £70! - and to pull it up for not offering the same quality or performance as far more expensive alternatives would be unfair. For a budget device, it’s great.

70% How much tablet can you feasibly get for under £100?
Source: Techradar EN→zh-CN Archive.org version
With a design and build that punches above its price-point and reasonable specification, the Gigaset QV830 is all the tablet you could possibly expect for £99, and actually surprises in a couple of regards. If you spend a little more, then there are more powerful tablets around, such as the Google Nexus 7, or more features to be had on the Advent Vega Tegra Note 7. However, if your budget is fixed, and you're not looking to play the latest and greatest games, then the larger (if lower res) screen and metallic feel might be enough to keep you content.

60% Gigaset QV830 review

How much should you expect from a £100 tablet? Cash-strapped people who want the style of an iPad mini for a fraction of the cost could do a lot worse than buying a Gigaset QV830. However, don’t think you’re getting everything an iPad – or even Nexus 7 – offers for less cash. Most of the specs are a year or two out of date and the Gigaset QV830’s performance is less than perfect. If you just want something to browse the web and play casual games on while lounging on the sofa, though, it’s a pretty great buy for the family. Ultra-budget tablets like this are far, far better than they used to be just a couple of years ago.
