Razer Orochi Mobile PC Gaming Mouse

I have VERY small hands, so what was a downside for others is a clear bonus for me. Giant, unwieldy mice are very obnoxious for me to use, and this is an absolutely perfect size. If you have small hands and want a GOOD bluetooth mouse, this is a very good option. It's pretty, it's smooth, and once you get it set up is amazingly comfortable. It also has a nice weight to it once you put in the batteries.NOTE: If you are not used to a high-DPI mouse, it will jerk all over your screen at first and make life really awkward. All you have to do is adjust the DPI down (which you can do on the fly, even in wireless mode) to something a bit more comfortable. A combination of that and adjusting pointer speed should handle pretty much whatever adjustment you need there.CONS: Synapse can be rage-inducing at times (It gave me MASSIVE problems with my Naga as well), but that's pretty much it. I was expecting full configuration options like in the legacy driver software. However, Synapse just sits there and essentially says 'Oh, look, you have an Orochi. Good for you.' It did install the necessary drivers (Plug in to the USB for a minute, install Synapse, run it, and then you're free to unplug whenever.), which was really most of what I needed it to do, but it would be nice to have a configuration menu for the thing. If you truly hate Synapse and want nothing to do with it, or it causes problems for your computer, the mouse CAN work right out of the box without Synapse installed, but you won't get updated drivers. What I'd recommend is download Synapse, have it download your new drivers, and then uninstall Synapse if it gives your machine any problems.ON REPORTED PROBLEMS WITH THE MOUSE SLEEPING: If you buy one and experience problems with it waking up from sleep too slowly, you can go into your bluetooth settings in Windows and turn off the 'turn off adapter to save power' option, and that should improve your response time. It's kind of annoying to find, but the setting IS in there, and it WILL fix most issues with the mouse lagging on wakeup. Nice thing is, it'll help it for your other bluetooth devices also. The mouse does go to sleep, but the only thing I've had to do to wake it up so far is just click once and it's immediately back and moving around at full-speed in less than a second. This does not appear to be a problem, at least not with the 2013 edition. I do, however, have a newer machine with newer bluetooth hardware, so that may also be a factor.

[edit: Updated a couple of things]I've been using Razer mice since the old Boomslang ball mouse released in 1999. I had the original Orochi and loved the Bluetooth, the many buttons to customize and the DPI options. For me, the Orochi 2013 is an improvement over the original. I need high precision and control for the type of work I do, so I don't really use the Orochi for gaming and can't comment on the lag. I do play Quake Live once and a while and really don't notice the lag issue many have a problem with.I think the Orochi 2013 is an improvement over the original. I really like the new texture. Compared to the shiny smooth sides and the rubber-type of top on the original. The Orochi 2013 has the same texture on the whole body of the mouse. Does not show finger prints or smudges and just feels very nice in your hand. The 6400 DPI Max is nice. You can set 5 stages of DPI and like the original there are 3 polling rates. The 6400 DPI is just a bit much for me. I have it set at 1200, 1800, 2600, 3400 and 5000. The sweet spot for me seems to be 3400 DPIOne issue I read about but have not had an issue with yet is the Synapse 2.0 software. Apparently the Synapse 2.0 configuration software requires login to configure. If their servers are down for any reason (or if you don't have internet access somewhere) you can't configure mouse. But with the onboard memory, once you've got your setting set you should be good. (I'm pretty sure. I haven't tested this theory yet.)One thing I noticed. In my office, the Bluetooth connection seems a bit off. Not sure what's going on really. I have a keyboard drawer at work and my laptop on a wooden stand. So there's like 2 wood barriers between the laptop and the mouse. The mouse is probably 14 inches below the computer. I'm getting a lot of jerky and laggy behavior. I will probably end up using the cord at work or take the laptop off the stand to see if that makes a difference. I know it kind of defeats the purpose of the mouse but the features, comfort and precision of the Orochi 2013 is well worth it. (edit: I took the laptop off the wooden stand at work and now the Bluetooth works great in the office and at home. Did not need to connect the cord)Here at home though. The mouse is literally like 8 inches from the laptop and it works amazingly.Edit: Another positive thing I wanted to mention about this mouse is that, unlike the original, you do not have to connect the cord to configure. And the Synapse software opens very quickly. And also, unlike the original I think you get the higher DPI and Polling rates in both corded and Bluetooth mode. Which is a very awesome plus.Only thing I really don't like and can't figure out how to change is that after a minute or so of inactivity, the mouse will turn off or sleep. You gotta click a button to wake it up. It takes mine 1 to 3 seconds to wake. Different from the lag issue, but annoying.And just a word of warning for the red / green colorblind. The lighting on the Orochi 2013 is green. Not sure if I'm going to be able to see the green when the battery gets low.Pros / Cons Summary:Pros:- Great uniform matte texture over entire mouse. (Don't know how to explain texture. It's not that shiny fingerprint magnet material.)- Higher DPI (up to 6400)- High Polling rates and DPT in cordless / Bluetooth mode- Improved software- Do not have to connect USB cord to configure mouse with Synapse 2.0 software.Cons:- Mouse will go into sleep mode after a minute or so. (have to click a button to wake it up) This seems to happen outside of any Windows Bluetooth settings.- Possible for some... Have to be online and the Razer 'cloud' server has to be up and running to configure with the Synapse 2.0 software. Has not been an issue.- Not sure about the Bluetooth. I had to take my laptop off a wooden stand, getting to closer to the mouse to resolve a minor jerky lag-type issue.
