Just wanted to write up a review of the MasterMouse MM520 after having used it for a day. I've previously owned the CM Spawn and Xornet II so as soon as the MM520 launched, it was a no brainer for me to order it right away. I heard how some folks that are diehard fans of the Spawn/Xornet might not be so sure about the changes for the MM520, so I wanted to just provide my thoughts on it (as a diehard Spawn/Xornet fan myself.)
Shape/Size: (1st Place: Spawn/Xornet II | 2nd Place: MM520)
Obviously, the biggest change is the shape and size of the MM520. I took a picture with my phone of the Spawn, Xornet II and MM520, side-by-side to give you guys a rough comparison -- take a look below and see for yourself.
As you can see, it's a little bit longer in the left/right mouse button area than the Spawn/Xornet. It took a little bit of getting used to coming from years of using the Spawn/Xornet but what I noticed is that I can pretty much hold it the same way as the Spawn/Xornet as I used to and it feels more or less the same. However, now for those of you with bigger hands and/or longer fingers, you'll have more space to choose where you want to rest your fingertips.
Also, with the increase in length I find that depending on how I hold the MM520, the back of it touches my palm which I'm still getting used to. (I think it's also because the groove on the left-side of the mouse for the thumb is a little deeper). With the Spawn/Xornet, I primarily used Claw + Fingertip grip, so the back of the mouse hardly ever touched my palm (that was just my preference; it helped me to do insane flick shots ).
The last thing related to the length is that the positioning of the scroll wheel is a little bit further than I'm used to. Previously, with the Spawn/Xornet, my finger would touch the top-half of the scroll wheel to turn it; now it touches the bottom-half. Overall, this is not too hard to get used to. I'd say the second point above about the MM520 touching my palm is the most noticeable change.
Weight: (1st Place: Xornet II | 2nd Place: Spawn | 3rd Place: MM520*)
According to the specs of all three mice, the weights are: (without the USB cable)
I definitely noticed the increase in weight. It didn't affect my aim as much, but it was noticeable. For insanely fast flick shots, a lighter mouse will always be better (it's physics!)
* Fortunately, I found a YouTube video that shows how we can remove the internal 12g weight. I think after I remove that, the weight will be perfect.
Sensor: (1st Place: MM520 | 2nd Place: Xornet II | 3rd Place: Spawn)
Awesome choice on the sensor CoolerMaster. It's just perfect. Don't think things can get any better than this.
Texture and Feel: (1st Place: Spawn | 2nd Place Tie: Xornet II and MM520)
To be honest, I kinda miss the all-rubberized feel of the Spawn. That was perfect in my opinion. However, with the MM520, I can see the benefits of the new material -- it's no-slip plastic and doesn't seem to attract sweat/oil. I guess I'll find out over time.
To those of you who love the rubberized grip feel, rejoice in the fact that the MM520 at least has that on the right side of the mouse for your pinky. I feel like the left-side of the mouse would've benefited from having the same rubberized texture as well (like the Xornet II).
Buttons/Scroll Wheel: (1st Place: MM520 | 2nd Place: Xornet II | 3rd Place: Spawn)
The MM520 has larger left/right mouse buttons and side buttons. Same tactile feel as the Xornet II.
The scroll wheel is better than the Spawn/Xornet II (better grip, smoother scrolling, slightly bigger.)
The only minus is there's only one DPI button now (used for TactiX which can act like a SHIFT key for all the buttons). It would've been nice to have two DPI buttons like on the Spawn/Xornet II.
Better than the Xornet II/Spawn software for sure. However, the LED editing UI needs a bit of work. It's a little confusing when editing each LED zone. It'd be nice to have some tooltips/help guide to figure out what each setting means. It's also not clear if I can set the LED lights for each DPI setting/profile.
I've somehow managed to configure it so that as I cycle between DPIs, the scroll wheel changes color to indicate the DPI setting, and after a few seconds, it goes to the LED settings in the software. I can't figure out how to change the different DPI indicator colors though; seems to be hard-coded as Red, Light Purple, Blue then Green.
The only other gripe I have about the MM520 software is that it takes a few seconds to save the profile after I click Apply. But fortunately, I only have to setup my mouse once.
TL;DR -- Should you get this or not?
Yes! If you previously loved the Spawn/Xornet line of mice and have medium/large hands or long fingers, you'll have an easy time switching to the MM520. However, if you have small hands and felt that the Spawn/Xornet was the perfect size already, then the MM520 might not be for you.
If you made it this far, thanks for reading the review and hope it helps!
Suggestions to CoolerMaster:
For newer versions of the MM520, here's some stuff I'd like to see in the future:
Overall, I think a mouse that has a shape/size somewhere between the Spawn/Xornet II and the current MM520 would be perfect (at least for me ). However, I think if CoolerMaster did what Zowie did for their ZA line of mice by offering different sizes (e.g., ZA11 - Large Size, ZA12 - Medium Size, ZA13 - Small Size), they can appeal to essentially every Claw/Fingertip gamer. Please make it happen CoolerMaster -- you guys are on track to having the perfect claw/fingertip mouse!
I think that by offering different sizes with the same shape like mentioned above could potentially solve this. For newer versions of the MM520, maybe an easier way of adding/removing the weights would help. For now, I think just including replacement feet would be enough for us diehard fans
Bring back a rubberized version like the old Spawn! I'll pay extra for it.
I'd really like to be able to customize the LEDs (all the zones) for each DPI setting and profile! Kinda like what was there for the Xornet II. I'm not sure if I'm doing something wrong with the software right now (like if that functionality exists and I'm just dumb) or it's not supported. Either way, the UI could use some work.
