because he is SS product ambassador or from SS company perhaps..... .

A4 Tech, good brand and not consider "CHEAP" if you really compare to those other china clones. But quality are there with special features that other including Logitech, MS, even smaller nice brand like Razer, SS..don't have.

Overall, i could say is:

Logitech: A good product but price at higher end but limited choice on gaming (only G5 and G9). Like Audi..

Razer/SS : mainly target for young gamers; price position on high price(to indicate its quality, and image of "rare" and expensive due to niche taget market and much smaller selling volume like Ferrari)

A4 Tech: providing choices and range from A to Z.... easily have 40-50 or perhaps 100 models to choose from, for kids, laptop user, lady, office users, including gamers. SO far I never seen a input devices can offer so wide range of products !!!!

But from economy pont of view, there can product so may rage means there have the volume on scale, overall can have much stronger capability to come out with something with much lower cost but with stronger features than other brand. Example: TOYOTA, HONDA...

Just my opinion. But I support A4 Tech since their ball mouse time since 90s'
