    Kingston DataTraveler Ultimate GT 2TB review: monster stick

    Kingston DataTraveler Ultimate GT 2TB review: monster stick We already saw it at CES, and in the meantime it has arrived at our test lab: the Kingston DataTraveler Ultimate GT 2TB. A USB stick with a storage capacity of two terabytes: please let that sink in for a minute. We only managed to get the same capacity on a 3.5'' hard drive back in 2009, however today it fits in our hand palm. Is this cool, 'just because', or is it actually worth having?  Read more

    TP-Link Deco M5 review: affordable mesh

    Review - Wednesday 08/16/2017 - 11:59 PM

    TP-Link Deco M5 review: affordable mesh Slowly but surely there are more and more mesh-systems available. After Linksys, TP-Link also follows suit with their Deco M5-system. Remarkable is that Deco, despite having three nodes, is a lot cheaper than the competitors we have covered thus far. This is in part thanks to the more straightforward technical implementation, which makes us wonder: has TP-Link found the middle-ground between affordable wireless coverage and performance? Read more

    Corsair K95 Platinum review: hail the new king

    Review - Monday 08/07/2017 - 11:59 PM

    Corsair K95 Platinum review: hail the new king It's been nearly four years since the release of Corsair's Vengeance K70 and Vengeance K95. Corsair was the first big manufacturer to use the floating key design with these keyboards. With this design the aluminum base plate is also used as a top panel, which means that part of the switches is laid bare and the keycaps seem to float above the keyboard. It turned out to be a hit, because not only were the aforementioned keyboards very popular, but other manufacturers also followed in Corsair's footsteps. The K-series was later expanded with RGB models and now the newest flagship from Corsair has reached our test lab; the K95 Platinum. Read more

    Eizo EV2456 review: classic format with a new look The majority of monitors have a 16:9 aspect ratio. However there are still a relatively small, but significant amount of monitors out there on the market with a 16:10 aspect ratio.
