Pros: Small, lightweight, comfortable, small usb receiver, nice grip for the mouse wheel
Cons: the main problem I have with this mouse is that sometimes it isn't very responsive, I'll move the mouse and there will be a delay of up to 2 seconds, even with a brand new battery in it, very frustrating.
Summary: If you don't get the double-click issue, it's a great portable mouse.
Pros: Great feel for a laptop style mouse. Solid click feel. Small receiver is very handy.
Cons: Every few clicks a single-click will register as a double-click. This is maddening. I've researched this and some attribute this to battery issues or drivers. Mine is brand new with brand new batteries. Middle click requires a strange amount of force when new.
Summary: Maybe your hand doesn't have a problem with the small and very tall mouse, but mine certainly does. It could be useful as a travel mouse, but I have seen mice that are small and still quite comfortable. The design team should have picked a more effective and comfortable shape
Pros: RF USB Interface. Long battery life
Cons: very small and highly arched. Makes my hand cramp if I use it for over five minutes. I do have large hands, but nearly all mice are comfortable for me. It is small for transport, but its size makes it unusable for me. Even though I hate the touchpad, I would prefer it to this mouse.
Summary: This is a REALLY small mouse, it has a good design, but it is just not worth getting...I have man hands and I can only fit my index finger and my middle finger on it. For 20 some dollars I expected more. Get the M310 instead, it is bigger and fits man hands better.
Pros: Wireless, good dpi, micro receiver
Cons: really really small...hard to control if you have big hands
Summary: Overall, I'm pleased with the mouse so far, but I hope the design is refined slightly to address the loose fit of the removable front face in future models.
Pros: Size is good for a travel mouse; It's a small addition to my shoulder bag when I need a mouse on the go. The USB receiver actually fits inside the mouse making it very easy to keep track of (the top face of the mouse below the buttons is easily removed via a latch on the bottom of the mouse, reve...
Cons: The build quality is a little weak compared to Logitech's larger mice. I use a Logitech MX 518 mouse when I'm at a desk, which feels great to me. The battery/receiver compartment of the M305 is a mixed blessing here, as the removable top face of the mouse leaves it feeling a little loose. The mid...
