I'd strongly recommend against getting a wireless mouse, or (more importantly) any mouse with a "laser" sensor.
For many years, gamers have been continuously fooled by gaming mouse marketing, specifically higher "DPI" numbers, because it's an easy-to-read spec that looks important and is represented in numbers. And the easiest way for the mouse manufacturers to achieve a high DPI is to use a laser sensor, while not giving a crap about acceleration or the other important aspects of a sensor. (DPI is only a measurement of the sensitivity of a mouse and has nothing to do with its tracking or accuracy in any meaningful way)
But laser sensors are in fact inferior to "optical" sensors, since they almost always have inherent acceleration issues or other flaws/imperfections in the tracking that aren't very obvious to most people, but overall make them less accurate than a "perfect" sensor. (Some optical sensors have these problems as well.) The only real benefits to laser sensors are that they're cheaper and track better on some unusual surfaces.
This has only become common knowledge in the most recent years, and is the reason why so many gamers give praise to mice like the Razer Deathadder 2013, the Logitech G502 and even older models like the Microsoft Intellimouse Explorer 3.0.
Buying a laser mouse in 2015 is just stupid, in my opinion. Even non-gaming applications can benefit from having a better sensor, especially if you learn to work without the built-in windows mouse acceleration (the "enhance pointer precision"option) that has plagued unknowing PC users for decades. Unless you really want a specific feature that isn't available on any mouse with a "perfect" sensor, I think you should do some research and look for those that have one. The three I listed earlier are decent examples. I personally use a Deathadder 2013 and I really like the feel of it (although I wish it would have more buttons).
The reason why I also hate wireless mice is because no matter how you put it, they always have more latency than a good wired mouse, and the practicality of not having a cable (that you could easily manage in an elegant way anyway if you tried) just isn't enough to justify the latency, possibility of interference/disconnection and having to charge/change the battery in most cases. (Unless it's for a laptop that you bring around a lot.)
To be clear, I'm sure you could make some valid argument for buying a laser / wireless mouse, but this is just my honest general recommendation.
Best of luck to you in finding a mouse that will suit you.
