On its own the Theron is a really great feeling mouse. On top of a very ergonomic feel to the mouse, you also get the rubberized coating to keep the Theron secure in your hand, even if it was a bit marred out of the box. Being it is a right handed mouse, I don't have to see that side of the mouse, so out of sight out of mind, but I will have to deduct points on the award chart for it.
With a few buttons on the bottom, and with only one of them truly needing use on a regular basis, the Profile button isn't such a big deal as you can swap that between games. Since you can set the polling rate in the software, you don't need access to that button a lot, and I have no need to lock out the side buttons either, so I can overlook the placement of those a bit more. What I did like was the on-the-fly DPI buttons on the top that are in easy reach. I thoroughly enjoy using the Theron as it is a good fit for my hand, but I did prefer to remove three of the 4.5 gram weights before I had a perfect fit to my gaming style. I even played around a bit with the LED lighting, but in the end I ended up sticking with the default red. There really isn't one thing that sticks out that I can complain about with this product.
Not to say that the Theron doesn't work without the Ladon mouse pad, but there is definitely a reduction in the drag from my basic cloth topped mats that I typically use. The dual layer top allows the Theron to retain its tracking with the ADNS 9500, but because the surface is in two layers, it may cause some LOD issues with other mice if they are set too low before you use them on the Ladon. I also really like that Tt took the time to seal the edges, and wrap them. I really do like my CMStorm mat, but even my arm rubbing against it has lifted the cloth a bit. With the Ladon, this will never be an issue, and I prefer that over the total space of a pad. I also really like that the Ladon is somewhat shiny on the top and the lighting of the Theron bounces off and gives it a nice splash of color outside of the lines of the mouse.
The cheaper end of the purchase, the Ladon, is going to set you back $24.99 if you are on this side of pond. Now you may be able to find larger pads at this price, only the ROCCAT pad even comes close to the Ladon as far as unique surfaces to try, and with the Ladon it is a step above any gaming surface I have tried thus far. To me the investment is well worth it. As for the Theron, there really isn't much more to say than go buy one. With no issues that I could find with the Theron, and the great feel it offers while using it, it almost makes the slight blemish on the rubberized surface sort of moot, but if I were buying it, I would expect this to come in perfect condition.
As a pair, with $25 for the mat, and as little as $58.94 for the Theron you really cannot go wrong with the pair whether playing RTS, MMORPG, FPS, or any other game type for that matter.
