The difference to use without a mouse pad was from day one enormous - I had no idea on what I refrained in recent years. The mouse runs loose and precise on the structure of the mouse pad. To this end, my hand feels constantly cooled. This is my opinion on the honeycomb structure that allows for better air circulation and which is located below the tread.
However, there are about 2 months use, the first signs of wear. At the edge of the Sharkoon 1337 XL dissolve small threads that will surely get bigger gradually. This is due to the area certainly a long-term problem that does not justify a new purchase in the near future. For the next few months I'm prepared grandiose with the Sharkoon. Another point of criticism is the cleaning. Due to the black area you see dust fairly quickly. Wiping with a damp cloth, however, means that the dust rather back and pushes. Here I have not yet found the perfect cleanability.
Nevertheless, there is of me a buy recommendation. Price and achievement are correct and particularly the feel is just great.
