Customer Reviews

Great Mouse For Gaming
The G5 is a durable, well designed mouse. I have been using it for over a year now with no problems. It's very comfortable in the hand and the ability to add or subract weight from it (by adding little weights that fit inside on the bottom) makes it perfect for the gamer. By adding or subtracting weight you can get the feel and the flow that you are looking for. Once you find that "sweet spot" weight, you will really get spoiled by this mouse.

It's not cordless, but for me that's a positive thing. I hate having to constantly add new batteries or sit my mouse on its charger. I can sit down and start using it with no problems. The mouse chord is plenty long and it's not real rigid like a lot of older mouse chords. So your movements are not hampered by the chord.

All in all it's the best mouse I've ever used... and I've been using them ever since they've existed.

Good choice for gaming
This is a very nice and well built mouse. As soon as you use it, you can tell that it's very well made. The new surface used on this model is very nice, non slip and does not attract fingerprints, unlike the earlier 6 button version of the G5

The option of changing the weight of the mouse seems gimmicky at first, but as soon as you start to experiment with the weights, you'll see that it's actually quite usefull.

The mouse tracks very well and the on-the-fly DPI changing works flawlessly. Also it glides very nicely which is even more emphasized when using a good mouse pad.

The reason I gave this mouse 4 instead of 5 stars is simply that the shape of the mouse will not suite every gamer. It is an awesome device for anyone using a palm or finger grip on their mouse, but someone (like me) that prefers the claw grip, mainly used in FPS games will find it a bit uncomfortable. You can get used to it though.
Also, the scroll wheel is a bit annoying. It would be better if it was a little wider and didn't have this utterly useless side scrolling function, which makes it a bit awkward to depress it.

All in all this is a great gaming mouse that is worth the money it costs. Every angle of it screams quality.
Just try and take it for a "test drive" before you buy it so you can make sure it's comfortable to you.

It's all in the size & shape!
The G5 is a very nice mouse, but if it dosen't fit one's hand, that dosen't matter. My hands don't work very well & I like another reviewer found the hump in the back just didn't work for me. I was amazed that none of the various mice specification say anything about their size, so here are the results of my quest to find out how big mice are:

V220 - 8.8 cm long
V320 - 9.8 cm
V450 - 10.5 cm
L6, L7, L8, MX400, & MX Revolution - 12.3 cm
LX7 - 12cmx 5cm x 2.5cm (long x wide x high)
MX518-12.5 cm
MX620 - 12.8 cm
G5 - 12.5 cm
G9 - 10.5 cm
Microsoft Basic Optical Mouse - 11.2cm x 5.1cm x 4.2cm
Microsoft Laser Mouse 6000 - 12.4cm x 6.7cm x 4.2cm
Razer DeathAdder - 12.6cm x 6.9cm x 4.5 cm

Sorry no shape factor. I bought the DeathAdder & it also is a very nice mouse & better yet, it works for me.
