Naga Epic Rechargeable Wireless Mouse

I got this mouse as an upgrade to my Logitech VX Revolution. I wanted to have a wireless mouse with extra buttons, and buttons this puppy has. But I was disappointed on several accounts: 1) The battery doesn't last nearly as long as on my Logitech Revolution. On the Revolution, it lasted ~3 weeks, but with the Naga, it barely goes 36 hours. That's with the LEDs turned off. I'd like to have at least a week, so that I don't have to worry about charging it every day. Having to charge my cell and laptop is enough; I don't want to worry about my mouse too. As it is, if I forget to charge my mouse one day, it will run out the next. 2) Waking from sleep mode is too slow. On the Revolution, the mouse reacted instantly, no matter how long it had been. On the Naga, it takes about a second before I see any response. 3) No tilt-click on the scroll wheel! I actually thought that the Naga had this, but it turns out that this feature only comes with the wired version of the Naga. 4) No mechanical buttons on the thumbpad. Again, only comes on the wired version of the Naga. 5) I have to manually switch between wired and wireless mode using a switch on the bottom. Can't it just detect when the cord is attached? 6) The buttons below the scroll wheel are hard to reach. I'd rather have them near my index finger, like on the old Naga, except with raised surfaces so I won't hit them by accident. And that's just the hardware. Even with those drawbacks, I'd still have given 4 stars, if it wasn't for the atrocious software. I'm using Mac OS X 10.9, and the Razer Synapse driver for the mouse is free, but the quality is alpha-grade, as in I wouldn't even call it a beta. Some problems I have with it: 1) The app takes half a minute or more to start up. If it starts up. And I can't really tell if it's doing anything, because it won't bounce in the Dock to show that it's starting up. 2) After you first see the window, it can take another half a minute to sync with the cloud, and it will not respond to you until then; you've got a blank window. So you can't configure anything for a whole minute after you double click the app. 3) There is a menubar item to select the profile for the mouse, but the only thing it's good for is launching the app. I can't switch profiles at all using the menubar item. It'll move the checkmark, but the mouse will ignore the new profile. 4) The app will sometimes randomly lose sync with the server, even if I haven't made any changes to the profiles. During this time, if you try to change a button assignment, it will create a duplicate of the profile without asking. And it's even better if you try to assign a keystroke to a button - it won't let you record a new keystroke. 5) When switching from wireless to wired and back to wireless mode, the battery meter will stop showing the percentage. 6) I can't save backups of my profiles to disk. Even worse, it looks like it saved the profile, when all it did was save an empty file. (I unzipped it and opened up the internal XML files. My button assignments were nowhere to be found.) 7) Using the menubar item is really laggy. I'll click, and it will beachball for a minute. 8) The app takes >250 MB of RAM. Seriously?! 9) It won't detect when Minecraft starts and switch to the profile for it. This works for other games, but not Minecraft. 10) When submitting bug reports inside the app, you get graphics glitches when the scrollbar has to appear. So why did I give 3 stars? 1) I like that I can adjust the DPI using a button together with the scroll wheel. A nifty meter shows a bar graph with the current DPI on-screen. 2) I like thumb grid! There are ridges on buttons 4,5,6 and 10,11,12 so you can locate them without looking. 3) Glowing numbers on the thumb grid. Great for starting out. 4) Replaceable side shields. They give you three of them, for different grips: claw grip, palm grip, and the intermediate fingertip grip. I use the fingertip grip most often. 5) Nice cable! It's replaceable, and plugs into the mouse and the dock really securely. Unless you're the Hulk, the tip isn't going to break off or get damaged, and the jacket is woven synthetic fiber. It won't curl into the way like a plastic one. 6) The dock is weighted and has a rubberized bottom so it won't tip easily. 7) Nice box! I'm serious. It opens like a jewelry box, and there is a custom foam insert for the different side shields and stuff. That said, I think this is still something of an upgrade to the Revolution, although I miss the tilt-click on the scroll wheel and the extra buttons under the index finger. For now, since I improvised a system to keep the cord tidy using wall hooks on my desk, I'm keeping it plugged in. Also, I'm thinking of switching to ControllerMate to configure the buttons. I'll lose the nice DPI adjustment feature, but anything's better than Razer Synapse. I've submitted bug reports for the above, but I've gotten nothing but automated feedback.
