Speedlink aren’t the first to arrive with an RGB edged mousemat but if you want something that matches your Speedlink RGB mouse or looks good on a desk then it may be worth a look.
The Orios mat boasts a range of colours and has a quick physical button on the small plastic edging to change them even if not using a PC. The mat is controlled via a fairly common micro USB to USB 2.0 cable which also hangs from this plastic edging sitting at the upper left side of the mat. The plastic is out of the way for the most part and the mat is so large that it should be able remain virtually un-noticed and the cable is long enough to run across the whole length of the mat and more, so should be fine for stretching to your desktop, even if it’s on the other side of the mat. As there’s no software you could equally plug this in to a USB powered hub or even a console such as the Xbox One to light it up via other means.
Aside from this you have a good quality mat surface that allows any mouse to glide nicely across it and a fairly good size to cover the whole desk at 910 × 420 with a 3mm depth. The base is Anti-skid rubberised backing which works well to keep the mat in place even in the toughest games.
Using the on/off button you can cycle through 7 different colours plus a pulsating rainbow effect which made my eyes hurt but would certainly get peoples’ attention!
Compared to some of the other RGB mats I’ve used (this replaced a large Luxcoms mat with similar designs) the Speedlink has a much better surface and stronger lighting.
