Hello! To start, please consider the following! This is the FIRST review I have ever done, so I will do my best to cover everything..... but PLEASE.. correct me if I'm wrong on a statement/tell me if I missed something! This is the first Optical Gaming Mouse I have used. I just moved from a Razer Naga Epic Chroma, so I am going from Laser to Optical, and Large/Wide, to Large/Thin. With that taken care of, I will start by breaking things down into the following: How well it 'feels'-the shape/size of it, button placement, etc. How well the sensor performs. How the buttons feel/perform/what they can do. (I apologize for the lack of video. I wanted to give a review but did not want it to take all day.) Starting with the SHAPE: Left side! It feels like they took the general idea of the Deathadder(although I like the right side of that mouse more... feels more curved.. preference that I picked up from the Naga Epic Chroma most likely), and added a thumb rest/wing(not sure exactly what to call it). This provides a good place to wrest the thumb that doesn't move when you move your mouse if your grip is very relaxed. If your grip is more tight/squeeze than relax/wrap around, then the wing will not matter that much, unless you have a extraordinarily large right thumb, where the curvature of the wing could get in the way. The buttons higher up on the left side also do not get in the way, at least from my experience from playing Overwatch with the mouse. I do occasionally bump the thumb trigger with my thumb, which can be annoying, but if you have small hands/do not want that trigger, then there are 3 trigger sizes for a reason. (long, short, and just a cover I think) The rubber grips on the left side... with the stripes in the design, it provides a good grip. HOWEVER, they do get quite dirty and are a little difficult to clean. The left button has a decent sized gap under it on the left side of it, right above the dpi trigger/clutch, and does not go down all of the way to fill the gap(probably intentional to give it a more sporting look). This is not a problem however, since the dpi clutch and the 2 side buttons kind of shield your thumb from that space. (And you would need very long fingers to reach that location) Right side! To start, I feel like the right side needs more... space filler/outward curve to it...(if you don't understand what I am trying to describe, think of the curve on this ')' right parenthesis. This kind of gives my 4th/5th fingers a bit of a cramped feeling after 20-40 mins of gameplay. (I am not sure of the exact time, but I end up frequently stretching my fingers because of this) I do not know if this was intentional(??) or if my grip style is just not fitting the style of this mouse. However, it is a little uncomfortable, whether or not it is on my end, or Razer's design. This might not be a problem if you have developed the (strange) habit of using your middle finger on the mouse wheel, and your 4th finger on the right trigger, which I have a feeling was the design purpose for this mouse. For the rubber grip on the right side.. they have the same design as the left side, and thus get the same, dirty/difficult to clean rating from me. They do provide a good grip, and extend 2/3 down the mouse. Other than that, the top of the grip seems like it doesn't quite fit. It feels like it wasn't properly fitted, and can cause irritation with some grip styles/if you leave one of your fingers on top of it. Sensor time! Let me say once more, that I just went from a Razer Naga Epic Chroma(which is glitching frequently) to this, 4G Laser, to a 5G Optical. That said, it performs as close as 100% as is possible to discern, unless you are one of the best players in the world for FPS games(and even they would have a hard time telling if this thing skips a beat). I have tried it on 400 dpi, 600, 800, 1000, 1200, 1600, 1800, think I tried over 2000 at one point. Other than personally not liking most of those and deciding on using 800 dpi as my main.. as far as I could tell, it performed perfectly. The sensor CAN track in increments of 50, down to a minimum setting of 100 dpi, and a maximum of 16000(who uses that??). There are 4 options for the dpi stages: 2, 3, 4, and 5 stages. I do not think that you can turn it down to 1 stage, without removing the sensitivity stage buttons and replacing them with some other function. You can hide the sensitivity stages and just set the dpi on a single slider(can also click on the number and type in what you want). It has 3 different ultrapolling rates, 1000, 500, and 125. You can adjust the DPI clutch to whatever dpi you want(or change it to another function... I have mine on hypershift at the moment). As far as I know, it tracks perfectly on both my fake-wood desk, and my $15 cheap 16.5"/13.5" cloth mouse pad. Time for the buttons! Lets start with the key feature of this mouse: The DPI Clutch. It has 3 different triggers you can put on it! Long was too large for my hands(medium to large hands), but it felt easy to press. Perhaps too easy but that's my opinion and my hand is too big for the large trigger anyway! The short one(middle size) is what I ended up using. It is a little harder to press(good for FPS games like Overwatch) and if it were very slightly smaller, would work perfectly with my hand size/grip. The final size is essentially a cap. I am not even sure if you can activate the clutch with it. However, if you don't need that button and love the rest of the mouse, it works! Time for Left and Right click! I find them a little too easy to press, and often accidentally shoot/use an ability when I did not want to. This can be inconvenient, or a death sentence, depending on the timing, but that could just be me! Now lets tackle the other two left-side buttons! I have to say this first. I love the tactile feel/sound you get from pressing those buttons. I don't like it for keyboards, but I love it for this mouse. It is not ideal if you are playing in the same room as someone who is trying to sleep(fortunately I don't have that problem!), but I find those buttons to be excellent! They don't get in the way, although the top of them could do with being smoother(not the side where you press them in. The top.) DPI Sensitivity stage buttons! They are thinner than my Naga Epic Chroma's sensitivity triggers, but still are easy to press and do not get in the way. They are also VERY slightly longer than my Naga Epic Chroma's sensitivity triggers. All in all, they work well, and I have no complaints! Scroll wheel! This one I will tackle in 2 stages. The wheel itself, and the wheel adjuster. Scroll wheel: Unfortunately, you cannot tilt-click this one(I tried it many times out of habit.. fortunately the build quality is great so it didn't break!). It is quite tall compared to other scroll wheels, and the grooved/whatever you call those things make it very slightly easier to grip/move precisely than my Naga Epic Chroma's scroll wheel. Not by much, but it is an improvement. It is also very easy to press down, especially if you set the tightness of it(more on that in a moment) all the way up. Wheel Adjuster! It isn't as big as the pictures led us to believe! It is VERY tiny, yet easy enough to adjust! When adjusted all the way tight, the scroll wheel makes a nice tactile sound, not too loud, just enough to hear it if you don't have loud music playing/have headphones on. It also makes it very easy to press the scroll wheel in. When adjusted all the way loose, it is essentially hypersensitive. Cannot even feel when one scroll is registered. Unfortunately, even when it is all the way loose, you cannot just flick it and have it scroll for a couple seconds. It stops as soon as you stop your flick/scrolling movement. It being all the way loose, I have to say it is very slightly harder to press in the scroll wheel without activating a scroll movement, but that might just be me. Atleast release an official statement regarding Oreo update. If we will get it(hopefully) then please mention the time frame or else please don't frustrate us as you have always done with updates. Forget the time frame, tell us if we will get it or not?
