Summary: I normally don't like to say bad things about products, but this is an exception. Firstly, pairing the mouse with the bluetooth adapter is hit or miss. I had to try 3 times to get it to acknowledge that I actually had a bluetooth mouse. Secondly, the sleep mode, which cannot be turned off. If you leave the mouse alone for 30 seconds or longer it shuts down. Think that's bad? Try waking it.
Summary: Owned the first Orochi for about 2 1/2 years now and I absolutely love it. Perfect size, decent on batteries (I game quite a bit), and great feel in the hand. Just ordered this one earlier this month to compliment my new Razer Blade and I found that I can't use rechargeable batteries in it. They cause my pointer to jump all over the screen almost to the point where I almost sent it back.
Summary: Not a fan of this mouse. I actually threw this in the trash rather than return it because I was so disappointed. Wireless operation is functional, but pitiful compared to my Logitech Laser which I have switched back to. I tried it with the cable but every few days it would lose it's mind and I would have to unplug/replug to get my mouse back. I'm not a huge twitch gamer, so perhaps I missed out on some of the features of this mouse.
Summary: This thing is TINY, if you wear size medium or larger gloves this mouse will be too small for you. With my fingers on the buttons the heel of the mouse is just under the base of my finger, the side buttons are completely useless because I have to stretch my thumb forward to hit them.
Summary: I know I put 1 stars for this mouse but I still love this mouse. Here is what I love. 1. Responsiveness and Precision. I love the responsiveness and the precision. With a high polling rate and high DPI, you definitely notice the difference in games. I previously used a wireless Logitech M705 and I love this mouse even though it's not for gaming. The ergonomics of the Logitech in my hand is awesome.
Summary: The bottom padding keeps peeling off, and when i'm using the Goliathus mouse pad it catches and starts ruining the mouse pad. Im not sure if the 2 times I got the mouse, it was bad luck, or if the mouse has a bad design. I hope other mice by them have a better design, and if there is a fix to this problem.
Summary: Endless update loop on Mac OSX 10.8.6. I am unable to access any software features that were so attractive. Bluetooth sleep is overzealous and makes the mouse difficult to use without the cord. Sometimes mouse operation is really choppy.
Summary: The driver must be _registered_ to a valid email address to work AT ALL. Once I got it working, it only worked once. When I went back to edit the settings again, it just presented me with a spinner. The whole reason I bought the mouse for the Mac was because it had a separate slider for acceleration. I thought this would have been ideal, since I don't really like the default acceleration profile of the magic mouse.
Summary: This mouse is not currently compatible with Apple's OSX Mountain Lion, although the specs. say 10.4 & above, I just got off the phone with Razer technical support (not the easiest number to find on their website) and the tech support person confirmed that Razer does not have drivers currently compatible with Mountain Lion. He did not have an estimate of when they might have one. He did not sound optimistic.
