Cons: USB Receiver is not good at all - my mouse was less than 6 feet away and suffered from link and lag issues. Mouse beeps everytime you push DPI button - for pete's sake why? I bought a Logitech keyboard and mouse combo for cheaper, and that mouse performed 5 times better than this one.
Summary: The only thing I noticed the dpi switch does do is move web pages forward and back when surfing. That might be nice, but using the icons never bothered me. My standard old $20 non-gaming logitech's and MS were better for gaming. Guess I'll just get another of those.
Pros: batteries included
Cons: No instructions about use of dpi switch. No difference noticed when using it. Tracking not smooth.
Summary: no better than and not as comfortable as a standard non-gaming $20 logitech or MS mouse the surfing forward and back surfing feature may be useful although clicking the forward and back icons never seemed a hassle b4
Pros: comes with batteries
Cons: no directions, notice NO difference adjusting dpi, the only apparent change using dpi switch is that it moves web pages forward and back when surfing
Summary: Okay, Zalman, my computer chassis is by them so I thought good quality. It is a good quality, however my only complaint is that the mouse will have somewhat of a spasm and beep for a good ten seconds, clearly its connecting then disconnecting. However, it has a nice weight.
Summary: Außer das Die Maus piept, beim einschalten und Einstellen, ist die Maus ganz gut. Die Tasten vor und zurück liegen auch auf einen gewöhnungsbedürftigen Platz aber noch ok. Sie liegt gut in der Hand und für den täglichen Gebrauch zu empfehlen.
