Razer Ouroboros Wireless Gaming Mouse
Razer Ouroboros Wireless Gaming Mouse

This mouse is mouse over-kill.
It's, like, putting on spoiler on cars. (y'know? spoiler is those wing-like thing on the back of race cars, it acts like reverse wings, so when the car goes fast, it pushes the car down to the road so it doesn't skip.)

It comes in a giant “glass” box. This box wastes your money.
The mouse actually comes with a ARM 32-bit processor. Yeah, a CPU in the mouse. It needs to compute things.
Wireless

• Wireless. → Good. Also can be used as a wired mouse. Just plug the USB cable directly into the mouse.
• Charging dock. → One extra thing to reduce your desk space. Though, the nice thing is that instead of plug/unplug the mouse every day, you just place it on the dock. Kinda saves you labor.
• Runs on 1 AA battery. 12 hours of continuous use. This means, you have to have the mouse sitting on the dock every 2 days.
buttons

3 buttons on each side. 2 silver colored ones, and beneath it is the 3rd button, called “DPI clutch-trigger”. Hold it down to temporarily increase/decrease the mouse's DPI. The clutch-trigger takes some pressure to hold.

Xah's Final Say
Think about the overall performance/price ratio. Then, this mouse is no good. Because:
- Currently a whopping ~$130 (note: prices can change dramatically because supply/demand). I'd consider the Logitech G700s a better mouse. Even if both have the same price tag.
- the symmetric design. That means, doesn't matter you are right-handed or left-handed, one side's buttons are going to become rarely used, uncomfortable to press, wasted.
- the 8200 DPI = Useless. 2k DPI is enough. 〔see What is Mouse DPI? Does DPI Matter?〕
- The adjustable size is nice. But, you can easily find the right gaming mouse for the size of your hand for half the price, without the adjustable parts and hassle.
Worst of all, Lots of terrible reviews on amazon. 15% of 1 star. 10% of 2 star. Many simply complain functional problem, such as wireless problem, charger problem, uncomfortable.
If this mouse is just $70, would i buy it? No.
if you are right-handed, a much better one is Logitech G700/G700s Mouse
if you are left-handed, get Razer's Left Handed Mouse .
Razer Orochi Mobile Gaming Mouse

- 6400 DPI. Laser Sensor
- Wired/Wireless Bluetooth 3.0 Connectivity
- 2 AA battery. 30 hours of continuous use. (no charging dock or wire charge)
this one is designed for on the go. Nice that it uses Bluetooth, so you don't need to plugin a extra USB wireless transmitter. When the battery is out, you can use it wired. (but it doesn't charge.)
I think a better one is
