Razer Goliathus mousepad review
 

The Razer Goliathus Gaming surface comes in two variations, the Control edition and the Speed edition. The one we are looking at is the Control edition in the standard size. The great thing about the Razer Goliathus is that it is available in three different sizes. If you want something a little bigger than the standard size (344mmx254mm)we are looking at then you can go for the oversized version (444×355mm) or if you do not have much room to spare on your desk than you can always go for the space-efficient version which is only 270 by 214mm's big. The two latter versions are both 4mm thick and the oversized gaming surface is 4.3mm thick.
