I used the corsair mm400 for a year or so. I personally liked it but you would have to clean it constantly for your mouse to glide. It can also slowly rip your mousefeet off if you get your mousefeet stuck when you flick your mouse off the mousepad and try to reset it. Other than that I think its a pretty good mousepad

Well, I recently ordered the Func F-Series 10XL mousepad. It's more expensive than the ones you've been looking into, but I've always heard Func mousepads were of high quality.
You could perhaps also take a look at some steelseries mousepads, the 4HD looks pretty nice.

I used to have a Roccat Sota, and while I love the texture and glide, I can't recommend it as it's not very durable.

I've owned a Roccat Alumic for around 18 months now, and I've loved pretty much every minute of it.
It's a tiny bit smaller than I would have liked, and you do need to clean the surface with a damp cloth once a day in addition to brushing dust off occasionally, but the glide is absolutely brilliant, and wear on both the mousepad itself and on my mouse feet has been minimal. There are two places you can tell the mousepad is not brand new, but only one is marginally relevant to surface feel/durability.

The mousepad itself is a sheet of anodized aluminum(approx 3mm thick), with two different polymer surfaces heat bonded to each side. The anodizing is starting to look a little faded in the spot my wrist makes contact with the metal, but that's just a cosmetic issue.
One problem you'll have with nearly any hard pad is surface wear, but it varies from one pad to another. With mine, for example the surface is less grainy and more reflective in the two spots that see the most mouse movement, but at the same time you can barely tell the difference in glide and texture so I really don't count that as a negative for this mousepad. Do keep in mind that the problem will be exacerbated if you allow dust to accumulate while using it.

However, the real deal-breaker for this mousepad, and a good number of hard mousepads is the edge of the mousepad on which you'll be resting your wrist. It took me literally 2-3 weeks to figure out how to use it without the bottom edge constantly making contact with the tendons in my forearm. Using the wrist rest was too awkward, so I've stuck to putting my old mousepad under this one, and leaving a 1.5cm strip of the old mousepad exposed at the bottom, on which I rest part of my arm.

In addition to all the above, keep in mind you're effectively getting two hardpads with this one. While I can understand why most people would stick to an ordinary cloth mousepad, I don't really see myself using anything other than a hardpad, or at best something like an Artisan Shidenkai.

A lot of hard pads have compatibility problems with mice (particularly the icemat), so make sure you do a bit of research on that front before your purchase.

icemats are great, but too small for me. same goes for the 4HD and 9HD.

i use the heaton qpad (435x365mm / 17.1"x14.4") with a G400 (tiger gaming mouse feet) and it's just an awesome combo. unfortunately the heaton qpad is very hard to find nowadays (discontinued), but there are plenty of options if you don't need a big pad like this.

i certainly vouch for the 4HD, 9HD or an icemat if any is big enough for you.
but in the end it's just preference, so i suggest taking some time to get to reviews on mats that catch your attention. prior posters had excellent recommendations as well, so i wouldn't be too hasty picking one!

best of luck finding a pad you like :)

edit: enigma ninja. take what he mentioned seriously!

I've had the G440 since Christmas and it's pretty fantastic, no compatibility issues or anything with my mouse
