  • Best Ergonomic Design
Style: NAOS PRO
I originally had the NAOS 3200, a great mouse that lasted for about 5 years with daily use and it performed admirably. Sadly it can't be ordered anymore but I will be switching over to the NAOS PRO, so this review is for the overall design of this product family. This has been one of the best designed mice for someone like me who likes to use the palm grip, and is great at preventing wrist and joint strain from moving and repositioning the mouse. The finger rests on the right side are such a rare but indispensable feature for my grip style. I used to have major wrist and joint pain issues with smaller claw grip-style mice frequently used at work. I looked non-stop for solutions until I found this design, which addressed all my issues by ensuring a comfortable and wide grip, where I can rest my fingers and move the mouse without gripping too hard and stressing my ring and pinkie fingers. Other notes: the plastic is high quality and durable, and had very minimal chipping/flaking. However, the rubber ring for the scrollwheel was less impressive and broke off after a couple months. The scrollwheel still worked fine, but it was definitely the weakest link. I had no other issues with the sensors, wire, etc. After 4-5 years the left click started being "glitchy" because it doesn't properly register when it's being held down, but this was after heavy use - a lightly used backup is still going strong, so I can't take off any stars, all things considered! ... show more

  • Always going back to Mionix...
Style: NAOS PRO
I'm a big guy with big hands. Most mice are relatively small for me, and eventually cause discomfort. This is my 3rd Mionix mouse and there's a reason I keep coming back! Not only does Mionix have great quality, but the mice are on the large side where you can comfortably rest your entire hand on the mouse without any fingers falling off. I tried a few other mice (Corsair, Logitech, non-name brand), and found myself just missing the sheer comfort that using the Mionix mouse gives. There arent a lot of frills, even though there are a lot of additional options with the software, allowing you to remap and create macros. The scroll-wheel is very serviceable, however thats where the fault began with my last Mionix mouse (scroll-wheel clicking stopped working after several years of gaming). It would be nice if they offered a wireless version of their larger mice, but now I have a backup wireless in the Corsair mouse if I ever need. If other mice leave your hand aching, Mionix is where its at. This is my first Naos Pro, but it feels right at home compared to the prior two Mionix mice I had. Claw grip and palm grip are both comfortable and easy. If you have SMALL HANDS, this mouse is probably not a good option for you, however! ... show more

  • This is THE BEST mouse. Period.
Style: NAOS PRO
This mouse not only feels great and is a lot wider and more comfortable, but the polling rate makes it so precise and smooth. I have never had a mouse as pin point accurate and easy to feel and control as this mouse. I purchased around 5 different gaming mouses and none of that compared. I tried the wireless Omen ambidextrous mouse, the RAT mouse, the Logitech g502, and Red Dragon mouse. It is very close to the Red Dragon in how it feels, but it is definitely wayyyyy more precise and easy to control. It has leveled up my aiming ability for sure. I am always going to stick to this brand. And amazing how affordable it is. ... show more

  • Great mouse... until the buttons started duplicating presses
Style: NAOS PRO
Just over a year after purchase, the back button on my mouse duplicates presses, causing a single back click to move two steps back. Of course, the warranty on the mouse is only 1 year, so in the trash it goes. Replaced by a Logitech that I'm sure will be more durable.

  • Great ergo for large hands...just not clean ones.
Style: NAOS PRO
I'm 6'2" with hands larger hands to boot. I'd purchased a NAOS before and, after extensive use, the mouse wheel started acting up on me. The rest of the construction was great and I loved working with it. After trying a few other mice I'm back here with the NAOS Pro. I love it's ergonomics, I love that it's wider so my pinky and ring finger don't have to drag on the mouse mat, and I love the feel of quality in my hand. It doesn't have a bunch of extra features outside of the, now pretty standard, extra buttons and DPI adjustment. My only complaint is that sometimes the mouse doesn't "stick" to my hands. That's a strange way to put it, but I feel like if my hands were just washed or are very dry the mouse just wants to slip out of my hands. It doesn't happen all the time and the rest of the mouse works well for me so I just put up with it. Most of the time it's fine. ... show more

  • My favorite mouse
Style: NAOS PRO
This is the third time I've purchased this mouse in 10 years. I've tried many different mice and keep coming back to this one. I absolutely love the design it is by far the most comfortable mouse I've ever used. Every finger has a place to rest, I don't have particularly larger hands and I still find this mouse very comfortable to use. It is great for gaming and is also comfortable to use in general for any purpose. I would highly recommend this mouse to anyone looking for an ergonomic mouse for gaming or for any task. ... show more

  • great mouse
Style: NAOS PRO
I have had mine for about a year with zero issues. The software works well and the mouse is super comfortable. I wish i had bought it sooner. The teflon pads are secure and show no wear. The paracord wire is super light as well. def recommend. I have owned steel series and Roccat gaming mice. This is my favorite. ... show more

  • Wish Mionix made more products!
Style: NAOS PRO
I owned a mouse like this back in 2007 and fell in love with the feel and comfort. I have other high-end gaming mice for 100 dollars or more, but I find myself using this more often. Why? It fits my hand like a glove, has a thumb rest, and glides across effortlessly. My only wish is they made this slightly larger. If you like claw-like mice, you can't go wrong here. ... show more
