[*UPDATE* Right after I posted this review, I started to issues with the wireless reliability. I deducted one star as it can still be used normally, but not in a competitive environment. The latency is not an issue, but I started having "jagged-ness" in large arm swipes that I could see and feel. It definitely has some polling issues that need to be sorted. See the photos at the end to show polling stability compared to an Xtrfy MZ1 Wireless. Hopefully it is something that can be solved with future firmware updates.]I felt like writing this review just because I felt it deserved some recognition for how great it really is. I was a big fan of the MM711 when it first came out. The shape was unique and the weight was extremely impressive. I stopped using it mostly because of the switches being inconsistent and the build quality was not the greatest. I had always been hoping they would make a version of this shape, but with a better build quality and better switches. They honestly exceeded my expectations with this new MM712.I'll go through all the changes that I think are worth mentioning from the MM711 to MM712.1. Wireless. The wireless tech on this mouse is perfect for me. I have not had a single drop-out mid game or anything odd. I've been using it for probably around a month in a competitive environment and in day-to-day use and haven't had a single issue.2. Hole-less design. The previous MM711 had holes to reduce the weight of the mouse. Having no holes helps the mouse be more comfortable to use for long periods of time and also helps with build quality issues. I definitely prefer having a solid shell, especially on the sides of the mouse.3. Coating. This is an underrated change I think. The coating on this mouse is so much better than the MM711. The MM711 has this really smooth plastic-y feel that was just really slippery over time and just not the most confidence inspiring grip. This version has a high quality feel slightly textured surface that grips up a lot when you start to get a little sweaty when gaming. It's very good in my opinion.4. Mouse 1 and 2 switches. The MM711 had some Omron switches that felt okay, but I think because of the build quality of the mouse, it had really inconsistent/mushy feeling clicks. In some games that have really heavy flicking, it would be obvious that your flicks sometimes would just not be where you wanted them to be because of the clicks. The MM712 has optical switches that are nice and consistent. If you have used Kahlil 8.0 switches in the past, you know how they quickly degrade over time. These have felt the exact same since I got the mouse and have never had a moment where I felt like I was held back because of the switches not working correctly.Now for the things that I would like to see changed (which isn't a whole lot honestly).The side buttons are a little stiff in my opinion. I'm not sure what switches they are, but they are okay at least. The rear side button takes more force the further you press towards the back of the mouse. I would like it to be the same force required to actuate it on all sides of the button. Not a huge deal.Another thing is the mouse wheel clicking down force. It's also a little stiffer than I would personally prefer. I use that button to ping in some games and it takes a pretty significant amount of force to actuate the scroll wheel click. Again not a huge deal since it still works perfectly, but the force required should definitely be a little bit less.Another issue I have is one that I haven't noticed before on any mouse. At first I thought my mouse sensor was dying because the liftoff distance felt like it was changing and wasn't working correctly, but I found out later that it was because there was dust building up right on top of the mouse sensor at the bottom of the mouse. I've never had that happen before on a mouse before, but it seems to happen pretty quickly on this mouse. I would recommend blowing out the dust like every day or so to make sure there isn't any on the sensor. Not sure what causes that to happen to some mice and not others, but that would be a small thing I would try and remedy as well (maybe thicker mouse feet would help mouse go over the dust and not pick it up? Not sure).Also a couple small things I would like to see updated would be a battery indicator on the wireless dongle, since most of the time I have the lighting effects turned off on the mouse to save battery life. Having it on the dongle would help not use nearly as much battery life as having it on the mouse, and it's still easily in view. I believe Razer has implemented this recently. Also sometimes I have a small software issues or something where if I changed the input on my USB switch, the lighting turns back on for some reason. It's almost like it selects a different profile for my mouse or something. I have to go back to my main PC and open the software back up to turn it back off. Not sure why this happens, but a small thing none the less. Usually happens if I click my USB switch to changes devices too fast.As much as people want to tell you that you need the top of the line mouse and spend 150+ dollars to be good at a video game, I can tell you right now you just do not need to spend that kind of money on a gaming mouse. This mouse is 70 dollars and checks basically every box the top dogs have. The only difference is they use a 3370 sensor instead of the 3395 (current gen as of this review) and some use 4K polling vs 1K polling on this mouse. As someone who takes gaming pretty competitively, you just will not be a better gamer on a more expensive mouse just because it has a better sensor or higher polling than 1k.The Cooler Master team for the mouse peripheral side of things should be proud of making this mouse. It's leaps and bounds of an iteration improvement over the last generation. I'm glad they bounced back with this after the MM731 debacle. Good job *thumbs up*
