One problem I had with my G-Wolves Skoll is that although it seems very good on paper, there are a couple problems. The mouse's shape is overall quite flat and that is not really something I appreciate. While playing games, personally I use a claw or palm grip, so I want my palm to be supported (this is also why the Magic Mouse sucks). I prefer the apex of the mouse shape, or "hump", to be near the back. After much research, I purchased the Cooler Master MM710.
Despite this mouse being quite small, you can really feel the hump. It rests naturally against your palm, which actually makes this mouse viable for daily use as well. The MM710 is an airy 53 grams. This makes it one of the lightest gaming mice in the world, for a cool $50. Aided by the PTFE mouse feet, this mouse is just about weightless in your hand during gameplay. It will definitely take you a while to adjust from the average 90+ gram mouse.
Despite being an ergonomic user, I find using this mouse quite comfortable. It should be noted, however, that it is extremely small. I found out when I started using it my medium-size hands (18cm) were too long to palm grip; my fingers were falling off of the front of the mouse.
One thing I want to note about the physical use of this mouse are the sides of the buttons. You see how they curve around the side of the mouse a little bit before ending? This makes the 2nd button brush against my fourth finger sometimes while it is holding the side of the mouse. However, the mouse switches themselves are very good.
The second big problem of the Skoll is that the mouse buttons had a lot of pre-travel. With mouse switches, you want the clicks to be crisp and actuate instantly, otherwise it is hard to achieve high clicks per second. Lastly, a great part of this mouse is the scroll wheel. While many gaming mice have slow, clunky scroll wheels, the MM710's was tactile but not very resistant.
Another aspect of this mouse that pleasantly surprised me was how well it was built. Usually mice with "honeycomb" shells have problems with the shell bending, creaking, etc. However, even when pressing the mouse very hard in all areas, there was no give at all except in the bottom. In one spot on the bottom there was a bit of give, and if you pressed it hard enough, it actually actuated the DPI button. This would be a problem, but since there is zero pressure on that spot, it doesn't really make a difference. Another thing I want to talk about is this mouse' cable. Although almost every mouse maker advertises the stock cable as "featherlight" or "speedflex" (actually Razer's marketing), Cooler Master is one of the only companies that actually delivers on that promise. The cable is a paracord, which means it is thin and light, but also has a loose braided housing that makes it extremely flexible, feeling almost wireless. One of the problems that plagues many gaming mice is a stiff and heavy cable, which is one of the reasons many people choose to go wireless.
This is an all-around impressive ambidextrous mouse. In a market heavily saturated with ~$50 ultralight mice (Model O, Skoll, Mira-M, etc), this mouse rises above with its shape, build quality, and nice buttons and scroll wheel. This is like all the other light mice, but I feel that it is the best in every area, and that is why I would recommend it for the best $50 ultralight mouse.
