I am someone who was very use to the Logitech G502 variants, and for whatever reason, the rubber on those things would start to bubble and the plating on the metal scroll wheel would start to flake off after like a month and get really nasty looking after 5 or 6, at which point my mouse would just look gross (not because it was dirty, but because it was literally falling apart) for another 5 or 6 before I bought a new one.

This mouse feels very similar to the G502 with a very similar feature set (or at least the ones I cared about - 3 buttons on the left side that can be easily used by my thumb, adjustable weight, toggle-able sensitivity, RGB color profiles. It does NOT have a freely scrolling mouse wheel nor 2 additional buttons on the TOP left but I never used those buttons anyway) and hasn't had even the slightest hint at bubbling rubber yet after about 5 months! High hopes for this.

My old gaming mouse died about 5 months ago, so I was forced to by this one when it was on sale.

It came with its own weight system in order to help gamers get use to a specific weight to play to their best ability.

But I prefer it nice and light. So it works still and I haven't had any issue with peeling or having any problems that other reviewers have had.

It is a bit pricey even on sale but it's a good mouse and I like it.

There was a reason I got this mouse. This mouse works amazingly. It has really nice a smooth tracking for video games, especially FPS games, and I also love how you can customize the lights on it with SteelSeries software. I would not recommend for people with smaller hands though. Overall, this mouse is a really good choice for those looking for a mouse that has customability and good tracking.

This is my second Rival 600. The connection became loose or something on the first one. I just found out today that Mouse Button 6 is not working on my second mouse while trying to program it for Apex.

This is my journey as a CSGO player with 19cm by 10.5cm hands.

I came from using the Logitech G403 for over a year. I liked everything about the G403, especially the feel of the clicks and its light weight. However, over time, I noticed I kept placing my ring finger slightly on the top right edge of the right button. I was most proficient gripping the mouse in a two-finger fingertip-palm hybrid, but after extended gaming sessions, I often would give my hand relief by placing all three of my fingers on top of the mouse, using my middle finger for the scroll wheel and my ring finger for the right button. Eventually, I came to the conclusion that the front of the mouse was too wide for me

As much as I liked G403's technical performance, I decided I needed to find a more comfortable mouse. After a lot of research, I decided to try the Rival 310 specifically because of its narrower front dimensions. Overall, I was probably 95% satisfied with the Rival 310. Given its overall comfort and narrower front end, I noticed I did aim better with it than the G403. However, after a couple of weeks of use, I came to three conclusions. First, although I liked the shape, it was difficult dealing with its drastic variation in dimensions depending on just where each finger rested on the mouse; I had to be thoughtful and careful when holding the mouse in order to feel consistent. Second, I felt like its top buttons were a tad too resistant, leading my fingers to feel sore after a normal night of gaming. Third, its idiosyncratic shape, with the hump further back, felt great for claw or palm grip, but didn't feel as good for my fingertip-palm hybrid compared to mice with the hump in the more conventional center area of the mouse.

I hesitated quite a bit with the Rival 600. Its slightly heavier overall weight, RGB ridiculousness, pointless removable cable, needless weight system, and superfluous second sensor for liftoff distance (which Razer and Logitech mice have been able to tune with *gasp* just a single sensor for LITERALLY years, which decades in mouse-years) all turned me off. I probably placed an order and cancelled it 20 times before I finally pulled the trigger.

Well, I am very happy I did. Immediately noticeable is that the plastic and silicone both have a silky, premium feel. The feel of the top clicks greatly exceeded my expectations as well; they feel almost equal to that of the G403. Most importantly, the mouse shape is exactly what I was looking for. While the 600 and the 310 are both Rival mice, the 600 is a new revision of the shape. The hump is more forward compared to the 310, and the mouse buttons rest slightly higher and flatter compared to the 310's extreme downward top slope. This all came together to mean a much more comfortable shape for my grip. It really fits my hand like a glove, and I'm very happy with it. With some tuning, lift off distance is better than the 310 but not better or worse than the G403, which one could also tune. The only relative weakness of the 600 compared to the 310 is that the side buttons are smaller and slightly less user friendly.

Hope this comparison was helpful!

EDIT (3/25/2018): Having tried this out for just under a month, I've decided to exchange it for another mouse. There are three reasons for this:

1. I have large hands, and my most comfortable grip position makes my thumb rest on the non-standard furthest mouse button. Yet, I keep wanting to keep my thumb on the smooth silicone part just behind it even though bending my thumb back like that isn't as comfortable. This discomfort, though minor, is present every day, every time I use the mouse.

2. The silicone material on both sides and on the primary top mouse buttons feels super premium and smooth. However, I think they also trap more heat. My hands get SUPER SWEATY when gaming with this mouse. The silver lining here is that there appears to never be any grime build-up on this mouse. However, this heat issue is a deal breaker for me.

3. The right and left sides of the mouse, due to the silicone, is super smooth, but both sides are tapered upwards, resulting in a slippery, difficult time whenever I try to lift the mouse. I have to pinch it harder than I'd like to, and over a session of gaming, my hands get really tired. This is further is exacerbated by reason 2.

I recently had to fix some stuff on my wife's computer, to which I had hooked up my Deathadder more than a year ago. Griping that mouse again felt sublime and reminded me of my 20s gaming with that mouse and, besides the double-click button issue that plagued the first couple generations of Deathadders, I had always felt that Deathadder shape was super comfortable. This is also when I knew the Rival 600 and I weren't working out as I had hoped.

My gaming mouse journey enters the next chapter. From Deathadder 3G (button issue) -> whole bunch of mice -> G403 -> Rival 310 -> Rival 600 -> Deathadder Elite.

If Steelseries every makes a lighter, more straight forward version of the Rival 600 without the unnecessary third mouse button, removable sides, extra weight system, etc. I'd go to that in a heartbeat.
