Pay attention to the reviews. The old one was amazing, this one is horrible. There's a reason the original is twice the cost.

Summary: I purchased the original Orochi in 2011 when I bought my laptop so I'd have a good bluetooth mouse. That version was amazing. The batteries lasted a long time, about 2 weeks with heavy use, and I didn't need to ever switch it off. The only issue I had with the mouse was the fact that I had to plug it in with the USB cable to change settings. About 6 months ago the mouse wheel button stopped working, so I couldn't middle click to open and close browser tabs.
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.
Buy a different mouse. Preferably, one that works.

Summary: I love the ergonomics of this mouse, but the software makes it unusable. I've been following Razer for years, this was the first time I could justify a purchase... and I was beyond disappointed. The mouse would fall asleep on League loading screens if someone had a slow connection, or in Path if I got up to get a drink while in town--well before an instance would even refresh. Sadly, gaming is probably the least-frustrating task to perform with this mouse.
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.
Terrible User Experience - Razer Synapse 2.0 Destroyed a Great Mouse

Summary: I've used both the old Deathadder, Razer Orochi and this newer Razer Orochi 2013. The hardware itself is very good and it's hard to find a good bluetooth mouse with high sensitivity/DPS. Unfortunately, with the new Razer Synapse 2.0 the user experience is so bad that it's not worth even using. Here is a common and reoccurring problem that I encounter and the workflow that I have to go through to correct it. It's all too common. 1.
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: I love this mouse, I really do. I really, really want to love this mouse and use it all the time. It has that nice weight of quality, the buttons are clicky and responsive, it tracks well, the scroll wheel feels nice. It's everything you come to love and respect if you own other Razer products. So why a low rating? Bluetooth. Bluetooth is where this falls miserably short.
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.
