Conclusion

No buy. Because:

• Way too expensive for its worth.
• Lack of buttons. Only 6 extra. 2 on each side, and 2 on top. The top 2 cram'd into a small area is basically gonna be useless.
• Symmetric design means, one side's buttons are going to be almost never used, so, effectively, you just got 2 programable buttons.

You better off buying a dedicated right-handed mouse, such as the

• Logitech G502 Mouse

Which gives you much more buttons you can actually use with right thumb.

Or, get this wireless:

• Logitech G602

Battery lasts you months.

Or if you really want light, get this one, only 80 grams, symmetric with usable buttons on both sides at top:

• Logitech G300s

If you are really awkward lefty, get a lefty mouse, such as Razer's left-handed gaming mouse.
