I need better than a 3 button mouse for Games other than games though, that one would be perfect.
I like having both dpi settings above the wheel, I never knew I needed it till I bought the Razer Lachesis but now I'm owned.
At first I thought you had taken a picture on tinfoil but now I see its a anti-static bag
I think the Razer/logitech arguments are a bit silly. Both mice have performance in mind and are suited for different hands. I don't think I've seen razer come out with a mouse with a large profile shape like the MX518/G5/G500. I also noticed that razer makes some left-handed models while I'm not sure if logitech does that. Personally, I enjoy the logitech MX518/G5/G500 over any other mouse on the market due to the weight modifications and the size. The side buttons help, too. I do however dislike that they keep the price inflated on the logitech series. A while ago 518's and G5's weren't as outrageous in pricing. I've also had a few issues with the cords becoming weak at key points over time. The only issues I've had with Razer mice is they simply do not function sometimes/die randomly. I've seen a few not work out of the box. It doesn't help though that razer brands itself as a GAMER CHOICE whereas logitech has always made things with office/durability in mind. Razer stuff feels of higher quality initially/aesthetically but almost always gives me the feel of less durable in the long run.
For everyday use, I use a Logitech g500/Das Keyboard (really really solid kb). I've been through a few of both mices, as I owned 2-3 deathadders, 2-3 mx518's, 2 g5's and 2-3 g500's. I've also gone through MULTIPLE gaming keyboards, and I find the biggest investment before a mouse that you can make is a solid mechanical keyboard, such as the DAS keyboard or even a keyboard such as WASDkeyboards.
edit: confirmed, you can't get a g500 in left-handed stylings. bummer! Razer does have left-handed mice available, though.
