I’ve got some recent mouse experiences!
I purchased a G502 about six months ago for my PC. I love it. While there’s no denying it’s got a funky shape, that seems to be the current trend in gamer mice (angles jutting out here and there). One of the things I especially like about the design is that it has a little nubby surfaces on the right and left sides (the right side has a bit more texture to it). Those surfaces let me know I’m gripping it in the right place. Plus, the left side has a concave surface and a little wing that juts out like half an inch at the base, so your thumb fits right in there and rests in a good default position that feels like “home.” This is a corded mouse, and the cord has a braided cover and is pretty long. It has a bunch of buttons including a tilt wheel (which are my go-to buttons for gaming). It also has a button that lets the mousewheel roll freely (this lets you scroll really fast through a long web page). I really like this mouse.
Over Christmas I purchased a laptop and I’ve been trying to find a good wireless mouse for it. I initially purchased a G603 since it seemed like a new model and it has some new connection technology (“Lightspeed,” whatever that is). This mouse feels like the opposite of the 502 - the mouse surface is smooth all over. The right side bulges out just a bit (more than the 502). The left side is sort of angled a bit so the mouse is narrower at the base than at the top. This means I was never exactly sure where my grip was relative to the mouse unless I looked at it (and when gaming, I don’t want to have to be constantly looking at the mouse to make sure I’m gripping it right).There doesn’t appear to be any sort of “home” position where you can grip the mouse and feel like you’ve got it in a good grip. And the smoothish surface means it can slip out of your grasp if you pick it up to reposition it. The Lightspeed technology lets you connect via Bluetooth or through a USB dongle. I connected with no issues with Bluetooth but after a windows update it refused to reconnect so I had to switch to the dongle. No tilt wheel buttons. I don’t like the feel of the mouse at all, and I kept looking for another wireless mouse from the second I got it.
Next I got a G602. It’s billed as a “Wireless Gaming Mouse.” It uses a USB dongle, which works fine. The design of it is more akin to the 502. It has the same little wing on the left side and so provides a good home position for your thumb. The surface is pretty smooth, but the thumb area helps you know you’re holding the mouse in the right place. It has a number of buttons, most of which I’ve not used - the extra buttons I have used are a couple of extra buttons to the left of the left mouse button. Those buttons are easy to hit. There’s a whole bank of them just above the thumb. I haven’t used any of those in any games yet. It does not have a tilt wheel. I’m happy with this but I really wish there was a multi-button mouse that had a tilt wheel (did I mention I really like the tilt wheel??).
If they ever came out with a wireless version of the G502 I’d buy it. But for now I’m going to stick with what I have.
