Review on 🐭 Corsair M55 RGB Pro: Ambidextrous Multi-Grip Gaming Mouse with 12,400 DPI Sensor, 8 Programmable Buttons - White by Matt Nichols

Basics: Large 86g wide viewing angle mouse in the style of the Sensei 310 but with a 3327 sensor capable of up to 12400dpi. Dual Zone RGB. Uses iCue software. A DPI button on top. Thumb buttons on both sides, a total of 8. The period of use before noting was two days. This is an unusually short timeframe for me to review a mouse, 4-8 days is normal, but I didn't want to put off reviewing while others are contemplating a purchase. The TL:DR is that there's a lot to like here, but the level of detail is unacceptably high, the sensor is entry-level and the product is overpriced compared to the competition. Advantages: + Safe shape. It is unlikely to be terrible for the palm, fingertip, or even a large claw. There is broad compatibility here. + This mouse can easily handle both 1-3-1 grip and 1-2-2 grip thanks to its shape, grip and weight. + Beautiful texture materials. Rough textured plastic on top, nice rubberized sidewalls that offer good grip despite the slightly concave shape. Some will find this rude. The materials serve their purpose. This is a very subjective category, but I think Corsair mice will always have my favorite materials from any brand. It's a shame that the claimed "awesome feeling" doesn't match the best products in general. + No pre-travel for primary clicks. Nice feel. Used 50M Omrons. There is no movement in front of the post, although they are connected to the body. + The main keys are not curved like on the Rival 110/Sensei 310. Not exactly comfortable grooves, but much better than the arched approach used on the Sensei/Revel types. + The middle click is light. Scroll resistance is light, decent tactility for FPS and browsing. + Low mounted scroll wheel for easy access for fast work. + The DPI button is very flat and good tactile. Don't worry about accidental triggering. + Mouse feet are average to good. Not the smoothest of glides, but no problems here. Mids: * The 3327 sensor feels good... when it's on the mat. I find it similar in performance to the 3330 but with a variable frame rate as opposed to the 3330's fixed frame rate. The touch sensor felt less accurate and less sensitive than the 3330 and 3360 and also felt more "jerky" when but that can come with a high level of detail. The good news is that it's an improvement over the 3325 in terms of tracking/accuracy and the mouse won't stay at $40. from the shell. Moderate spam.* Good placement of the thumb buttons on the main side, the concave shape on the opposite side increases the chance of the button being pressed unintentionally, which only happens a few times, and you can disable/enable the buttons via software. I would welcome a toggle switch for left/right/none/both on the bottom rather than relying on the software for this function. * Glossy finish on the bottom. Can scratch easily.* The tail feels a bit heavy in the hand, not critical, but I found myself holding the mouse further back to compensate. It's not a cock too heavy and won't pose a problem for many. not on the left side of the software interface where most mouse controls are located.* "RGB Dual Zone" means the logo and tiny silver DPI indicator behind the scroll wheel. It's barely up to date, but you can control the color of both lights. RGB transitions are a little rough, and colors from the software don't translate very directly to the mouse in terms of hue. For example, the software must display distinct reds in order for the mouse to display solid orange.* The mouse's rear protrusion will delight many palm-lovers, and fingertip gamers may find it gets in the way. I had no issues, but while this mouse is significantly shorter than the Model O, the bump definitely makes it feel like it has more bulk overall. While the base dimensions suggest a medium-sized mouse, I'd say it's in the large mouse range.* Even compared to the lighter O model, the M55 feels a bit empty. I think it has something to do with more volume and weight distribution over a larger area. Personally, I don't think this should be a problem for people, even if they do notice it. Bad: - Some play between scrolling steps. Not enough to ruin anything, but the annoyance comes from anything without this game (like Glorious Model O) - Scroll wheel rattles when shaking mouse. In the game with headphones it is not noticeable, but without them there is a problem. The scroll on my copy dangles and dangles from the sides. Combined with the play between scrolling steps, the scroll wheel alone is considered a generally decent build quality. Significant movement before and after pressing the DPI and thumb buttons. The feel is good, but there is a bit of a mess before and after. A small drawback, there are many worse things. - iCue software. Huge, unintuitive, dubious EULA. Pooh. I don't see the point of re-entering the same complaints I've made in the past with all of Corsair's other recent mice... take my word for it or try it yourself. The cable is pretty stiff. So far I've seen better in a few $15 mice. Definitely below the expected price range. The DPI button is too far behind the scroll bar to be very convenient in-game. They could place the DPI meter behind the button instead of the other way around and make it much more convenient for my flashbangs. The worst physical aspect of this mouse is the lift-off distance. LOD is a solid 3+ DVD out of the box. Tested on hard and soft dark surfaces. Worse, I didn't see an option to set up LOD in the software even after installing the latest version. Perhaps this option can be added later, as this one aspect of the mouse annoyingly makes it unsuitable for gaming and introduces a massive amount of sensor jitter that needs to be corrected when the mouse is placed back on the mousepad. It might be possible to fix this with firmware, but for me at the moment, LOD is a deal breaker, even without considering relative sensor performance or price. To be clear, this LOD is worse than any 3325 mouse I've tried and is on par with the worst of the old 3050 mice. Bottom line: disappointment. Normal shape and clicks, great sensor performance, good materials, average build quality, terrible level of detail, uncompetitive price ($40) at release. This is the first mouse I've tried with the 3327 sensor. I didn't care and wish I hadn't. Let's get down to some hard facts. Corsair basically took the basic design of the Sensei/FK1, made it more like a speargun with side handles and called it Good. Two or more years after those companies released their mice, Corsair eventually copied its winning formula with a lower-quality product. For an extra $10 and sacrificing some thumb buttons, you get a Glorious Model O with an upgraded sensor, hence RGB lighting. , software, clicks, build quality. The Model O currently has the highest nit-noid rating I've given. This mouse wants to play in the same league when it grows up. In the future life. For $8 you can get a far superior Sensei 310. For the same price you can get an unimproved but competitive Eluktronics Luminosa with 3389 sensor and paracord. For the same price, you get the Logitech G403, which objectively beats this mouse out of the water in most if not all categories for the vast majority of people. For $10-$15 less, you can get a Rival 110 with an equivalent shape, slightly inferior buttons and materials, but better software and RGB, and a more competitive sensor. until it reaches $25. If you are a serious gamer just stay away. I also disagree with some of Corsair's marketing efforts here. The packaging says "high performance sensor" but doesn't say 3327 is used because they want you to think of 3360. Pixart's own site says the 3327 is an "entry-level" gaming sensor. How did Corsair improve sensor performance by doubling the 6200's DPI? It's not like this. Actually, it probably cost the performance, but at least they can put "12400 DPI" on the box, right? If you represent a company that is unwilling to disclose the type of sensor used on the packaging, what is the sensor in your mouse doing? It's amazing comrades. Of course, it's possible (obviously) that Corsair didn't want to make a "better mouse," and it's possible that they're only now "catching up" with mice that were released two years ago (or not). Even so, Corsair needed to know the market the mouse was being released for. They are a little cheating with this product, they are a little greedy and they are definitely playing ignorance if they think they can sell this product as is for $40. There is no rational, ethical or economic way for this mouse to stay at $40 for any significant period of time. (On the other hand, Californians are becoming known for their mathematical prowess when it comes to business... and Corsair is based in California...coincidence?) There's always a chance that something's wrong with my copy, but I doubt it. Have to see if other reviewers can confirm the same issues. The M55 is a full-featured mouse, so it's impossible to give it an A in terms of value, but hopefully the examples above give an idea. an example of why this mouse is rated the way it is. The M55 mouse is not legally competitive in the current $25+ mouse market and is at a disadvantage in every competitive esports arena I can think of. It doesn't deserve the "professional" in the title, it rather deserves the "amateur". I love supporting American companies, but right now I don't even care about Razer products, and Corsair really needs to up their game. $40 Bang: $25 D+Bang: C+Nit Noid.
