Logitech M125
[My Weapon of Choice]
I have had this mouse for quite a while now, without issues.
As a result of using it, I've grown accustomed to its palm grip style.
Pros:
1000 DPI
Comfortable, even for extend play (despite my large hands)
Very responsive
Retractable cable for easy transportation
Mouse wheel is pronounced and has a rugged-like feeling for easier access and a more 'precise' feeling.
Cons:
No side button (which would be very useful - especially for a gamer)
Its size may not be conducive to all hand types.
Its cord may have a shortened life to its re-tractability function.
Summary:
A decent. well-performing mouse for anyone who uses a Laptop or Desktop PC.
It's durable, and because of its size, an ease for travelers.
