Ah I've been waiting for this thread. Heed my advice young pursuer of a mousepad, for I shall take you to places you've never dreamed of.
You are using a g500, you have a laser mouse, that thing tracks on pretty much anything. However, we are greedy, and we want it to track as best as possible.
I'm going to toss out 2-3 options for you, since I have tried a lot of different pads and right now am extremely pleased with the one that cost me the most (figures).
Ratpadz Cheap, and godlike. This is the best solid pad you will find for the money, however, if you want to be a boss, you need to step it up. Steelseries does make some good mouse pads, and since they were mentioned, check them out. HOWEVER, please take a look at Razer, this is one thing they do very well. Razer pads are really good.
Now, if you are still reading, then you must want a good piece of equipment. Using a g500 means you will want something that responds well to laser. While laser works great on most surfaces regardless, one surface stands out the most. A
white surface. Here, are the 2 best mouse pads for your G500, your Mamba, your Deathadder, Lachesis, I don't care.
Razer Destructor Obviously, select white. This is the one I use. Loved it with my mamba, love it with my G500.
Megasoma This is an expensive product, I've never used it, it's different material, but it's got great reviews. Go check out hard forum about this shit.
I nominate the white destructor btw. The Mamba glided on the Destructor like it was on air, was amazing. The G500 with full weights, not so much. I bought the Destructor for my mamba, but no longer have that. It's 100% the best pad for that mouse. Since G500 has different feet, check out steelseries and the other pads shown. I still believe nothing will track like white. BTW, there is more to getting a REAL mouse pad over not using one at all, it's not just about the surface or friction. As mentioned, take a look at hardforum, they just fucking track better and the mouse will work overall better. If you FPS at all, and aren't using at least a 20$ pad, you aren't as good as you could be. BTW think Ratpadz still has a 5$ off going on, just add to cart and it might be cheaper.
