At first when I got the mouse out and installed it on the testing rig, I was thinking I would be looking at just some other optical sensor based mouse, not so much with a marketing hook, but I wasn't sure what the IR sensor had to offer yet. As soon as I grabbed the software and got to setting the mouse to fit my needs specifically, I was very pleased with what I had found. I played the full scale of DPI, and while painfully slow at the lower-end, it is very accurate, and the heft of the mouse with the weights all installed allows it to stop on the proverbial dime. What was rather pleasantly surprising is that even as I moved up to the 4000 DPI maximum setting, none of the accuracy is lost, and there isn't a single tendency to overshoot the mark, or even jitter when trying to double click on the icons, it is just smooth as silk to work with, it really is. I was already a fan of the original design of the Theron, but I would trade that Avago laser sensor for this IR sensor any day of the week. It just tracks that well.
The mix of internal switches doesn't bother me; they just assigned switch types to the priority of use. Omron's for the most important buttons that get used most. HC switches for the side buttons that get used more than the DPI selection buttons that were backed with the ZHIJ switches. I didn't find myself needing to swap profiles during the games, and I set the polling rate for my settings via the software, so the fact that the buttons are on the bottom is of little consequence to its performance or functionality there. I really do like the new splash of red with the buttons on the Theron Infrared, but there is one thing I really need to stress. The LOD is set high out of the box to allow you to use any surface under the Theron IR. The issue is, the more detail the pad has in its texture, the lower the LOD needs to be set. Be careful though, if you set it too low and move somewhere else, the LOD could be too low for that instance and the IR sensor may have issues tracking. Keep this in mind if you do plan to use this mouse on multiple systems with different mouse surfaces.
The fact that this mouse is going to be available at the very reasonable asking price of $59.99 just makes the entire package that much more appealing. I mean, not only do you get one of the best tracking mice I have ever had under my hand, you also get pretty comprehensive software to give you all sorts of options to set up the Theron IR. You can store up to 40 Macros across the five profiles, and keep it all with the mouse on the onboard memory. The options are truly endless, and you also get the handy zippered bag to protect this menial investment in your gaming future.
It isn't very often that I can get through a whole review without picking something apart, but with the new Thermaltake Tt eSports Theron Infrared, there is simply not one thing that I would say needs any work or any sort of improvements. When you get a design right, you simply get it right, and that's what's happened here with this mouse.
