Pros: It's corded! I prefer corded mice.

Has a pretty good "feel" to it, with the wide base and the rubbery texture over the entire mouse surface.

Wheel also has the same rubbery texture, which has more grip to it than other wheel mice I've used (gaming or traditional). I also prefer how this wheel 'clicks' for each position, instead of being a free-wheeling mouse like Microsoft uses. I prefer to have that 'click' feedback so I know when the wheel has moved a position.

Very light weight, along with the large pads on the bottom, so it really glides across my Steelseries QcK+ like it's on ice. It's really light though, almost to the point of feeling cheap. It doesn't feel cheap per se in terms of grip or button feedback, but due to the light weight; it just feels a little cheap.

I like the light that indicates the DPI settings, changing from red to white to green to yellow to blue (indicating lowest to highest). I typically leave it on mid-point (green) for most usage.

All buttons have a good, meaty click to them, and nothing feels flimsy. I like how the buttons are placed; specifically, how the DPI buttons are right by the left mouse button, and how the 2 side rocker buttons have a good size and stick out "just enough". (Logitech seems to be infatuated with making their side buttons have nubs on them, and I hate it; I'm glad Corsair did not make their buttons like this.)

Braided USB cord adds a little extra flair and completes the package look. Cord is extremely long, but of course I'd rather have a cord that's too long than too short.

Light customization is a neat feature. Nothing I really require, but, neat nonetheless.

Mouse is plug and play and works without downloading and installing the software, albeit with limited functionality. (Windows treats it like all the buttons are just buttons, and the sensitivity does not adjust.)

Works great for not just gaming, but also graphic design as well. Despite being an IT guy now, I still do freelance on the side, and the DPI switching comes in handy quite a bit with Illustrator and Photoshop when I don't feel like switching over to my Wacom tablet.

Cons: I'm deducting an egg for the software. A mouse, especially of this caliber, has 2 facets - the hardware, and the software. It's really good on the hardware, but the software is another story.

I'm glad to see that they finally added the software under the Downloads section for the Sabre RGB. When I first received the mouse, the only downloads listed on the Sabre's page were the user manuals. I had to dig around their site to find the download which was listed under another mouse (and just crossed my fingers that it would work, which it did). Anyway, they now have it listed under the Sabre RGB downloads, so that's good for new owners now.

Anyway, the software is a mess. As a long time Logitech user, Corsair's Utility Engine software is a cluttered mess. I have not spent a lot of time with it customizing it, because I'm coming from an MX518 and the biggest thing I wanted to keep for sure was the DPI switching. I had to actually set the Action to use the DPI switching in order to get the Sabre RGB to switch DPI in the games that I've played with it. Once I did that, I was able to switch the DPI. Until then, the only time the DPI switching worked was within Windows, just general desktop/productivity usage. I dislike this, because out of the box, the MX518 does switch DPI in anything, even without Logitech's software being installed. You can further customize the MX518 with the software, but it's not required to take advantage of the feature of the mouse like the Sabre RGB requires.

There are a lot of bells and whistles here with the software, and a lot of things that you can customize. There is a PDF guide that comes with the software, and they do have their user forums which are full of helpful people and many Corsair reps to help out.

But as a whole, the software seems a little overly complicated. Maybe once I spend more time with it and become more familiar, it'll come easier to me.

Other Thoughts: Longtime Corsair owner here - the first name brand RAM I purchased was Corsair due to their fanbase recommending them. I've never been disappointed with a Corsair product over the last, oh, probably 15 or 20 years. Memory, many power supplies, RAM fans, USB flash drives, cases, and now a mouse - they make terrific products. 95% of my experience with them has been flawless, and the few times I've had issues, their support replaced the products under warranty quickly and easily and I was back on my way. From a customer support perspective, Corsair is aces. They've never let me know, and I will continue to seek out their products no matter what I'm buying.

Again, I've been a Logitech guy. My MX518 has been in use for probably 8 years now; it's a tank of a mouse. I've taken it apart once or twice and cleaned it, but hardware + software, the MX518 has been a tank.

The Sabre RGB is definitely good enough to finally retire my MX518. It obviously has more bells and whistles, and offers a lot more customization, so I will stick with the Sabre RGB from now on. The Sabre is more wide and flat (lower profile) than the MX518, but it's still a great mouse. Again, the hardware is solid; I have absolutely no complaints about the hardware.

I wish the software wasn't so complicated to me right now, but I'd rather have the extensibility and customization (and not quite grasp it all yet), than have the software be limited and be a crux.

In closing - excellent mouse. Forgetting the bells and whistles for a minute, and speaking merely from a 'feel' - this mouse has a very good feel. Setting up the mouse in a fairly basic manner (DPI switching alone), I'm totally happy with the mouse. I've played around with the colors a little, but for the most part it's the same now as it is out of the box and I'm totally happy with it.

Excellent mouse, very good build quality, excellent price. I'd definitely recommend the Sabre RGB.

Pros: Lots of storage for a pretty attractive price.

Thick and somewhat built well, would easily take dropping and probably a wash cycle or two.

Capless, retractable design means you won't have to keep an eye on a cap to protect the USB interface.

Has a loop for a lanyard and a blue activity LED.

Good USB 2.0 performance.

Cons: Abysmal USB 3.0 performance.
Comparing this device to a Voyager GO 64GB flash drive, the GO outperforms it by nearly double at all tasks, and the GO is not that much more ($7 as of this writing). I tested in 2 ways, using a synthetic benchmark as well as several 'real world' tests using file transfers to the drive.

Using UsbFlashSpeed.com's free benchmark tool, the Voyager Slider had an average of 14.15 MB/s write and 61.99 MB/s read using a USB 3.0 port. Comparatively, the Voyager GO achieved an average of 29.67 MB/s write and 111.1 MB/s read - more than double the write speed and nearly double the read speed.

In testing 'real world performance' using several types of file transfers using TeraCopy 2.27 Free, the results are as follows:

-Copying the Windows 10 Technical Preview for Enterprise ISO (3.71 GB), the Voyager Slider had an average of 17 MB/s for a total time taken of 3 minutes, 39 seconds. The Voyager GO transferred the same ISO at a rate of 34 MB/s (double the speed), taking 1 minute, 53 seconds (nearly half the time).

-Copying some music files, 118 -V 0 files equaling 0.96 GB, the Voyager Slider had an average write of 13 MB/s, taking 1 minute, 17 seconds in time. The Voyager GO had an average write of 19 MB/s, taking only 52 seconds. A smaller batch of files, 17 320kbps files, the results were more even: the Slider had a write of 26 MB/s taking 6 seconds, and the GO had a write of 30 MB/s taking 5 seconds.

-Finally, copying 561 pictures and mp4 files (6.45GB in size) taken on my Note II from my synched Dropbox folder to the Voyager Slider had an average write of 15 MB/s taking 7 minutes, 9 seconds, while the Voyager GO had an average write of 28 MB/s taking 3 minutes, 55 seconds.

In other words, the Voyager Slider does a lot better at handling small batches of files at a time, but sustained transfers and/or large file transfers really drag the performance down quite a lot.

The Slider also does not come with a lanyard 'string' (despite having the spot for one), and while it is a retractable, capless design - the actual USB terminal is exposed in the front, leaving dust, dirt, pocket lint, and anything else to easily seep into this socket.

It is also very large. Granted, the size will give it some shielding and survivability from drops, but, it will most likely block surrounding USB ports on your computer. It did fit OK (but barely) in the front USB port of my Kenwood head unit in my truck.

Other Thoughts: The Voyager GO is only $7 more (at this time) and offers (in most cases) double the performance, as well as a smaller size and MicroUSB connectivity for your smartphone. If you're in the market to buy a USB 3.0 drive, I'd definitely recommend the Voyager GO instead of the Voyager Slider.

The Slider is serviceable, but, I think it would be an easier sell if it was roughly $20 cheaper, leaving the GO as more of a stretch/price premium over it.
