I've owned this mouse for less than a week, so there is certainly a chance for problems to develop in the future, however initial observations point to this being an extremely high-quality product.Appearence: The mouse is BRIGHT red (think tomato red, not quite blood red) and shiny. It features a bright blue LED within it, which bleeds through around the buttons and from 'vents' on the sides. In low-light conditions, it looks absolutely amazing. The only flaw is the right mouse button, it seems a bit thinner near the rear of it, which means that the blue light seeps through. In dark conditions, that area will just glow a bit. Looks odd, but meh.Feel: Well, i bought this to replace a microsoft notebook/laptop mouse i'd been using for a year and a half (excellent small (tiny) mouse, btw) so it's going to take a while for me to get used to the Nidhogg. specifically, this is a full-hand mouse, not a finger-mouse. Because my previous mouse was so small, i'm used to 'holding' it naturally in only my fingers (i didn't 'palm' it while using it). The Nidhogg, however, only really fits right when you have it in your palm. In addition, ti's a 'claw-type' mouse, where you need 3 fingers. (one for left, scroll, and right) so it's a bit odd at first. However, those complaints are mostly just me adjusting to a new form factor. Otherwise, the scroll wheel has extremely defined 'clicks', and is very responsive. Clicking the wheel takes more force than most mice, but not a terrible amount. The DPI button is below the scroll wheel, but don't worry about accidentally changing it. It requires a fairly large amount of force, so regular use isn't going to trigger it. Unfortunately, the mouse is a bit lighter than I had hoped. My tiny microsoft mouse is the same weight, and since the Nidhogg is about 3 times the size, i'd have expected a bit more heft.Responsiveness: Well, this mouse is insane. all 4 DPI modes are distinct and extremely accurate. The red light for the sensor is extremely bright, but does not bleed through at all. The side buttons can be awkward to reach, but require enough force to prevent random/accidental clicking.Drivers: zero drivers included. There is absolutely no support/software shipped alongside the mouse...because you don't need any. This is quite literally plug-and-play. I unplugged my pervios mouse, plugged the Nidhogg in, and instantly it was usable. There is no included button-customization tools, but the staff at Mibru recommend xmouse (google it).Shipping/customer service: I called up the company to ask a few questions before purchasing, and they were extremely helpful and courteous. In addition, they ship via USPS priority mail from their warehouse in California. It took only 3 days to get to Philadelphia, so don't worry about the estimated ship time amazon gives you. it's actually much faster.Depending on how it ends up working in a longer-term setting, i'd absolutely recommend this mouse to people.Since there are no other reviews on this product, I'd like to briefly share my experience with this mouse.The mouse was delivered via FeDex and was well packaged.First impression I got was that the mouse was somewhat bigger than I expected.Still it fits my hand comfortably and I don't have any major issue with that.The blue LED emitted throughout the body looks pretty cool and I really like it.One minor issue is that even when I put my computer into a sleep mode (Windows 7), the light remained on.But this may be hardware dependent and I'm fine with that anyway.Below are a couple of features that are not in the item description.- The mouse emits red-light at the bottom (it would be better if it was invisible, though).- The scroll wheel does not support horizontal scrolling and the middle (scroll wheel) button feels a little bit stiff requiring slightly more force than other mice I had so far (Logitech ones).- The DPI button (right below the scroll wheel) seems to toggle among four different DPI settings but the light only either turns on or off. So it's not quite easy to see at which DPI mode it's in but you can feel it by moving your mouse a little bit and it won't be a big issue for most people, I guess. Anyway, I could really feel the difference in the sensitivity by clicking the DPI button even with the default Windows 7 driver (I'm not sure if they provide separate driver for this).I didn't have a chance to try it with any games and will not comment on its performance with games.Anyway, I believe Nidhogg is a new company in this gaming mouse business and seems to be doing a great job.Overall, the mouse feels great and looks very stylish and for the price I paid (around $30), I'm quite satisfied.I'll update my review later if I have any other findings or issues.... that's what I'm talking about. Plug n' Play, no Drivers. Works on all OSes.I'm not much of a big gamer, but I do play a bit. However, I am a graphic artist and do enjoy high-resolution mice. I was on a quest to find a really good high-resolution mouse, but for the right price. I had found the Logitech Optical Gaming Mouse G400. Although it wasn't laser, it was priced perfectly. However, it had no drivers for my Mac. Which was very disappointing since I've been using Logitech for years on Macs and PCs. Never did I have a problem with no drivers for my Mac and in most cases, never needed a driver at all. Oh, sure, I could've bought USB Overdrive, etc, to run it. But, that's not how I work. I want a device that plugs and plays into everything and never do I want to use a third party software to use another third parties device. Just not into it. So, I had to send it back. So, then I went on a new quest. I start looking into Razer, etc. I found nothing in a reasonable price range. Until I found this Nidhogg Gaming mouse. I admit, I was skeptical at first, etc. But, I took the leap and I don't regret it one bit.I "palm" the mouse and I find it comfortable for me. I've gamed and used it for graphics, works great. The resolution button is cool. The settings are 600DPI, 1200DPI, 1800DPI and 2400DPI. About the only strange thing you'll find is that when you boot up your computer, you'll find that the mouse defaults to 1200 DPI. So, you'll have to click the resolution button twice to max it out. Other than that, prefect for both my gaming and graphic needs at a good price.
