I am a electronic & computer geek, so I tend to stick to the "name brands". I do make an exception from time to time and with this product, I'm glad I did.
This mouse is ergonomically correct. It fits and curves naturally with your hand. That's not the only feature that separates itself from the rest of the pack. It also has a nice compartment, underneath the mouse, for stowing the usb device.
The mouse top is a perfect design. There isn't any hassle of taking off the mouse top. It is held on by magnets. It pops right off and goes right back on.
The battery compartment is another feature that was designed just right. There is a plastic holder, that slides into a slot, to hold down the batteries. This makes for easy battery changing.
I would recommend this product to anyone. It is durable and correctly priced.
