So my new G7 came in today (yay for free shipping and getting it next day, thank you Memphis distribution centers). First thing I did was plugged her up alongside my MX1000 for comparison on my desktop.



As you can see, it's a bit differently shaped than the MX1000. The thumb rest is a bit less pronounced, and the overall curvature is slightly different. It still feels really good in the hand though. Then there are the other obvious differences like the forward button and the "scroll cruise control" buttons are gone (sidescroll is still there). No huge losses there. Then there are those two buttons behind the scroll wheel, which are the DPI switching buttons. The mouse can switch on the fly from 400, 800, and 2000 dpi. Now when I fired it up, it was initially in 2000 DPI, so it was crazy sensitive to movement (more than any other mouse I'd ever seen). I put it down on 800 DPI and it felt very similar in movement to my MX1000 (MX1000 also runs at 800 DPI). Only real differences in feeling probably come from the different feet, as well as it weighing probably 1/2-3/4 what the MX1000 does when you have the battery in it. Also, the battery indicater lights, similar to the MX1000 ones, also double as the DPI indicators. They're orange when they're showing DPI, and green/red when showing battery status.



Now, this is the receiver/charger unit (charges off USB, no AC power needed). It's nothing really fancy. The receiver is completely encased in that protruding part, which is simply a little USB dongle (so it can be used alone as the receiver if need be). The battery slot is below that, and it has a little blinking green light to indicate when it's charging. There really is nothing fancy about this unit. It's simply a USB exension cable that also draws power for the charger. Thus, it will also work with other USB devices, if you're not using the mouse receiver in it.

Now, the real test of this thing's beauty. I decided I would give it the standard gamer's test, so I fired up CS: Source. First thing I did was crank my in-game sensitivity down fairly low, obviously. Then I started up the game, and switched the mouse into 2000 DPI mode (800 DPI is much more suited for navigating menus if you're like me and have your Windows mouse sensitivity set really high). Immidiately I notice how well this thing works. Every tiny movement is so precise, and I'm immediately popping bots in the head left and right (I felt I wouldn't play online just yet since I've not played CS in ages). You really can notice a huge difference at 2000 DPI if you're a gamer. There's really not much more to say. It just feels that nice.

I really have to recommend this mouse to anyone who plays lots of FPS's, or is a mouse whore like myself and wants a great, very portable wireless mouse. Only slight annoyances with it is that the scroll wheel and its button is a little stiffer than the MX1000's, but nothing too terrible. Or, if you want a cheaper, wired solution, go with the G5 which is essentially the same thing, but wired. You'll probably only use the mouse in 2000 DPI when you're gaming. 800 DPI really is better suited for general desktop usage. Luckily, that's not an inconvenience because the switch is completely on the fly. 800 DPI also shouldn't suck the battery down as quickly. I think logitech advertises 10 hours of battery life at 2000 DPI (10 hours of actual movement, it'll go into standby much like the MX1000 when it's not moving). Then of course you get two batteries with it, so when one dies, just switch them and pop the dead one in the charger and you're good to go. For comparison's sake, the batteries are 600 mA, 3.7 V, while the MX1000 battery is 800 mA, 4.2 V.

All in all, this thing quickly became my favorite mouse ever in about 10 minutes, lol. Oh, and I think it goes without saying that the wireless performance is flawless, as was with the MX1000.

Oh, and cost was only $58 after rebate from Buy.com. They've also got the G5 for a pretty good price as well.

One word... nice!

I would actually consider a G5 or G7 if they weren't A) Ridiculously expensive and B) incompatible with my Icemat Rev 2. Or at least the MX1000 was--I'll have to look it up to make sure the G5 and G7 are, but I'm 99% sure they are.

who would you ever want to set the mouse to anything lower than its maximum resolution?

So it's not stupidly fast--I imagine it would be at 2000 DPI. I use 1600DPI all the time though...but that's just me.

That and 2000 DPI really isn't necessary for standard desktop usage (save for maybe photoshop). 2000 DPI will also drain the battery faster.

I think they use the same 832-852 nm infrared laser that the MX1000 use, so I'd doubt they'd work if it doesn't.

So what are your plans for that MX1000?

Still using it for main desktop stuff. Actually got my G7 mainly for its great combination of portability, quality, and having a rechargeable battery. It's the first good rechargeable mouse to come with a USB dongle receiver that isn't so tiny that it's a pain to hold. It's actually my new mouse for my laptop, that I'll also use when I play FPS's on my desktop.

I've got a MX310 at 800dpi. But mine's wired, I just don't like using wireless mouse/keyboard/joystick.

good review, I've considered getting a G7 to replace my MX1000, after damaging my wrist I've really began to notice the weight of the MX1000.

Only thing I thought I'd miss is the extra thumb buttons, I currently have 2 out of the three in use almost all the time, one for close program and another for switching between programs, although just thinking about it I hardly ever use side scroll so could asign one direction for app switch..

anyway, on the laser front I think they are using an updated version of the laser that is in the MX1000, basically the same just modified for extra dpi.

Same laser, different imaging optics and electronics I'd imagine.
