Great value with a few flaws
This is extremely decent for the money.
I've used mostly a Razer Mamba 2013 edition, coming from a 2008 one, as my main mouse for about 12 years, along with a Logitech MX Master 2 on another system. So as a general rule, I like higher-end mice, and those two were what I had previously decided were just about right for my grip.
The switches in both Mambas were starting to fail so I ordered the Rival 310 to be a spare, and maybe a keeper if I liked it. The first thing that I found disappointing was that it actually has an optical sensor - Steelseries' marketing of a '1-to-1' sensor had given me the impression that it was laser. Interestingly, it seems to have a more complex setup than most optical mice, and frankly it seemed to perform more on par with all of my lasers than even my nicer optical mice, so I got over the prejudice very quickly.
I really like the shape of it, it's maybe not perfect, but it's about equivalent size to a Razer Mamba or maybe a Deathadder. Very much not set up for left handed use, though, if that's important to you. The standout bit of build quality is how solid the switches are - it's a nice crisp click, without needing excessive force. The slightly taller nature of the ergonomics, and the little tilt towards the side are definitely on the better side from a wrist fatigue perspective. It's certainly comfortable to use for an extended period of time.
I've only had it for a day or two so far, so I can't speak to the longevity, but the build quality seems pretty decent for what it is, and the materials are nice.
The only other gripe I had was that out of the box, it had an absurdly low default sensitivity, even turned all the way up in Windows. Now, once I downloaded their driver pack, I could make that comfortable and disable the garish LEDs as well (some people might like the very deep game integration that it also enables, but it's not to my taste). However, this means that it's probably going to be unpleasant to use on Linux machines, and I resent having to add another piece of bloatware just to get core functionality working - something that I never needed to do on the Mamba or the MX Master, despite their software flaws.
Ultimately, it really is very comfortable and certainly 'good enough' for proper gaming. If the caveats I mentioned are not important to you, the only thing still in question is how well it fits your hand. If you like slightly larger mice (or normal circa-2005) and use a palm grip, you'll probably be pretty happy with it.
Granted, I found it for about $17. At retail price, I wouldn't be as happy about it, and would probably try to find another older Mamba. Nevertheless, it proved to me that you really can get a decent mouse for not a lot of money nowadays - it's miles better than the Gigabyte Ghost ones half my family uses.
