[Evaluation/Discussion] CMstorm Xornet (56k warning)

Today I'll be evaluating a mouse known as the CM Xornet. Before I dig right into it, here are the listed specifications.

Cable Length: 2 Meters / 6.56 Feet

Dimensions 75(W) x 107(H) x 35(D) mm


As we can see, this mouse has a max CPI value of 2000. While that may not seem like a big deal, it was a fair indication that this mouse would be utilizing the latest ADNS-3050 optical sensor from Avago Technologies. There are and have been previous sensors rated for 2000 CPI, but they were either a variant of the Avago's 6010 Lasersteam (G5, X5, etc) or simply boosted via lens size (Zowie EC. 1600 CPI x1.25 vs x1.0 Magnification). The "Up to 160 IPS" and "23g Acceleration" sealed my assumption as those are the listed specifications provided by Avago. Moving on, we can see that this mouse is equipped with both Omron's and quote "Ultra Swift" Teflon feet. Ultimately, my main focus was it's "Right Handed Ergonomic Claw Design". I honestly didn't know how this would work out as thin ambidextrous mice are generally the preferred choice for the claw grip and or playing style.


Shape and Size


IMAG0290.jpg

Well that feels... natural?

Starting off with the shape, there is nothing I can really compare this mouse to. Well, that's if you're not counting the sister product known as the Spawn!

When first released, I didn't really see or think the shape was that appealing. I mean, CM had stated that the shape was "designed" for the right hand claw gripper, but I just couldn't see it. Of course I was wrong!

While it may not be the most attractive and simplistic mouse in the world, the sheer design of this mouse is absolutely brilliant for my variation of the claw grip. In fact, after busting out and playing with a few of my ambidextrous mice, I found myself craving the Xornet's Egro-ness.

Also, I would like to touch on a point that hasn't really been brought up. Might be due to how the groves are designed, but when I'm clawing the Xornet my mouse is fairly straight. Maybe it's just me, but when I grip other mice like the Microsoft Wheel Mouse Opitcal, Logitech G100, or even Steelseries Sensei, etc... they're always slightly tilted to the left and I find myself forcing my hand straight.

As for the size, I took a picture of other popular gaming mice for comparison.

Weight
Unfortunately, I do not have a scale but going off estimate, it's a little over 80 grams~ With full cable, CM states the mouse weighs a total of 142g which is the same as the Spawn.

Cable


Jumping straight into it, the cable is fully rubberized and is similar to an Intellimouse or WMO when it comes to thickness. Flexibility is a little stiffer, but it's not as bad as a majority of the braided cables I've encountered.

Ultimately I think the Xornet's cable is fine, but would prefer a thinner and looser variant. Luckly, that may just happen with later batches of this mouse according to carter.

Build Quality


This is going to be tricky as I don't want people to get the wrong impression of this mouse. I'll start off by saying that the external build quality is fairly good, but that's only by my definition. It isn't going to compete with certain mice in the $50-60 range, but it really doesn't have to considering the MSRP price of $29.99 USD. I understand that mice like the G400 go on sale, but were dealing with two different shapes at that point.

Overall it's good, but don't expect a Porsche at Fairlady Z pricing.

Problems:
-I don't know if it just effects my mouse, but the back button or mouse 4 gets activated if you press too hard on the side of the shell, just slightly under the actual switch.
-The buttons may be considered loose or too light for a lot of people. I personally like them.

Main Microswitches: Omron D2FC-F-7N
Side and Middle CPI Switches: TTC 159 series
Scroll Wheel Encoder: Unsure, but looks like a newer variation of TTC.
MCU: Cypress CY7C64343
Sensor: Avago ADNS-A3050
Lens: Avago ADNS-5110-001 x0.80 Magification

Internally, the mouse is well build. Soldering on main PCB is excellent. It actually comes from the same factory that the Steelseries Sensei and other popular mice are built in.

The only concern I have is the side button key and switch placement being a little off. It may have something to do with how my Xornet clicks when extent pressure is applied to the shell.


Tracking Quality


Black QcK:


Untitleddsds.png

Left 1000 CPI, 1000 HZ + Right 500 CPI, 1000hz.


2kdpi.png

2000 CPI, 1000hz.


xornettrack.png


The Sensor is okay at 500 and maybe 1000, but it gets fairly jumpy on it's 2000 CPI setting. Even though the option is there, I don't feel that this sensor should have been giving the ability to scale up that high. Higher end mice with sensors like the 3090, 3080, and 9500 show consistently better tracking quality (multiple surfaces) at or around 2000 CPI mark than what the Xornet can pull off at 1000 CPI.

In its defense, this is labeled an entry level sensor and it's unsurprising that it shows.

Note: All of these paint "test" are set at 1000hz.


Max tracking speed.

Where a major problem starts.

The mouse can perform exceptionally well, but it's extremely sensitive to surface color. With the default firmware, I found the mouse to skip around to larger swipes on darker surfaces. Lighter surfaces like my older talent felt better when it came to max tracking speed.

With Enotus, the Xornet could register decent counts, but it isn't really accurate as the program reports much higher than what the mouse is physically capable of. Admittedly I haven't had much time testing other hz settings, but it's more or less the same story.

Instead of giving estimates, I rather turn this into a discussion thread and do testing on a 1 by 1 basis. As it stands, It's max performance is generally "low" even while compared to mice with the same sensors. I can only assume that it's a problem with the MCU and or firmware.

Overall I recommend firmware v52 for a balance of lift off and tracking speed.


Lift Off Distance

-v50. Default firmware. Very annoying. Over 3.5mm for sure.
-v52 Balance of lift off distance and tracking speeds. Around ~2.5mm. (Personal recommendation)
-v55 slightly lower lift off than v52. Not recommended since the mouse takes a noticeable performance hit.


Angle Snapping/Prediction/Drift control/Correction


Low, or what many people call "predictionless" or "OFF"

Polling rate

Can be changed by holding down mouse 4+5 in cohesion with the CPI toggle buttons.

Selectable 125-250-500-1000hz. Defaults at 1000hz.


Final Thoughts:

-The mouse has decent internals and build, but I feel that it's brought down by the current firmware and MCU combination. While it's tracking isn't going to compete with a 20 pin 3060+, it does its job at both the 500 and 1000 CPI setting.

-At MSRP price, there aren't many competitors, but mice with a generally higher MSRP are within the Xornets current price bracket on such sites like amazon making the mouse a less appealing buy.

-Overall, I think they did a good job with the actual hardware and hope to see a potentially solid firmware in the future.

Many Thanks, I've been waiting for this.

The actual malfunction speed on black pads is appaling, somewhere around or under 1.5 m/s. Too bad because the shape and the build quality is perfect. I have one that I bought but left it in its box until CM releases better firmware versions for it.

Another excellent review.

Reading this review after watching a Kinzu v2 abomination on Youtube was refreshing.

Does the Puretrak Talent count as a dark or light pad? Because my Xornet works fine on mine. Btw I can also make the back thumb button click by pushing in the rubber grip just below the button. I don't know how you discovered that though.

I guess both since it has light and darker weaves

I discovered that issue while trying to open the mouse. (didn't realize their was a screw under the sticker)

Thanks for this review. I'm using this mouse too and find it great, especially for the very low price. (paid 19€ for it)
I came from a Abyssus and had to get used to the very sensitive mousebuttons (Abyssus mousebuttons are rather stiff and tactile), but I got used to it.

I can press the rear thumb button through the rubber too (seems like a common thing).
But you have to apply alot of pressure to do it. So it's not much of a problem, exept maybe when you are raging hard and squeeze your mouse in you rage biggrin.gif

Thanks for the heads-up on the Firmware version. I'd only tried v50 and v55 up to this point. v55 just didn't feel right - I think the max speed was way too low. v50 was very uncomfortable to use. It wasn't that the LOD was too high necessarily, it was that the perfect tracking height was very low, but the max tracking height was horrible. At 1CD the Xornet was already losing tracking speed. The real problem is that it was still "losing" tracking speed at 3CD's. So it had a good 3+mm of distance where the mouse would kind of track, but kind of not. I've never really been bothered with LOD on any mouse (that I owned) before this one, but the Xornet was damn near unusable for me out of the box.

Just from a few minutes of playing around with v52 I can tell it's a huge improvement over both v50 and v55. All of this is on my white Artisan Shiden XSoft L with polling speed at 1kHZ and 1000 CPI. I have not run into any problems with the max speed except on v55 - probably because I'm a fairly high sense player (around 12-15cm/360), so it's not likely that I'll be hitting over around 1.5 m/s.

As for the side button issue, I couldn't duplicate that on mine at first. I grabbed the mouse in my usual style and couldn't set the buttons off. Then I grabbed it as hard as I could ever see myself doing in-game and I still couldn't set it off. Then I grabbed it ridiculously hard and I finally managed to get it to click (and incidentally lost the first version of this post). I cannot see myself ever setting off that button accidentally by grabbing the mouse for what it's worth. Of course after a few years of use that might change, it is something I'll have to keep my eye on.

One additional thing I could note is that my scroll wheel had a rather irritating clicking noise when moving up (and sometimes down). It has gone away after about two weeks of use, so I'm not sure if it was even worth noting, but if it bothers anyone else, there is a good chance that it will be gone after a bit of use.
