Do you like small mice? Do you want a small light gaming mouse?
Small mice are really hard to find. I like small mice. I have short-ish fingers and I like a fingertip grip. A few year ago my beloved genius laptop gaming mouse died and I couldn't find a decent replacement. I ended up buy 3 of the Asian versions of the razor salmoza from South Korea. They were almost too small and my KVM didn't recognize it properly taking 30 secs to switch between machines.
I saw these on the CCL site for under 5 so I bought one (27 on Amazon when I bought it). When I tried it, it was beautifully light and exactly the right size to hold lightly in your fingertips. The sensor seems accurate and it has no tracking issues. I haven't been playing e-sports twitch stuff but it's fine for Battlefield/Dying Light/Metro Exodus type games.
What's not to like? Well this is a cheap mouse and the thump buttons show it. They're cheap plastic. Also the overall feel of the mouse is not as quality as a Razor mouse. The buttons are not as sweetly clicky. I also read not to expect that they would last forever. (My razor mouse is 5 years old and showing no signs of stress)
So.. rather than worry about this I bought a couple more. That means when this one dies in a year or two I don't need to start the whole search for a light, small, accurate gaming mouse all over again.
Pros: Great for small hands. Light, small and accurate. Switchable dpi. Good compatibility with hardware. 3 button + 2 thumb design. Very, very, VERY cheap.
Cons: Not the best build quality. Cheap thumb buttons. It's not really 5.. more like 9 'cos you'll buy 2 to make sure you have a backup.
Overall, I've had this for 3 months now. It's small, light and comfortable. It works well with my KVM and it's managed to replace my Razor mouse completely, which is a surprise. All for under 5... err 9.
Think of it as a laptop size gaming mouse.
