Have never bought a product from Razer, but I'm glad I did! This is my first gaming mouse and it has instantly improved my skill in fps.
- Very comfortable for right-handed use
- Highly accurate (Am currently only using 1600dpi)
- Ultrapolling up to 1ms
- Software customisable
- Not ambidextrous
- Software has to be downloaded from razer's website
- Wired (I don't see this as a problem but it might be for some)
For this mouse I would recommend the Razer Sphinx Gaming Mat, which is supposed to be best for laser mice (have just ordered one).
Can't recommend this product enough. It is a very good mouse.
