Edit:
If Steelseries engine ****s up my computer again, I'm going to completely smash this mouse.
Get in there boots and all. Never hold back your anger when you've been ripped off in some disgusting way by these Razer-wannabes. Shame they (manufacturers) started to form a group of maladjusted input devices, designed to irritate more than anything.
Sometimes I am tempted to place some of them on my driveway, pour some petrol over them and light them up into a black stench of death - never to harm anyone ever again.
I believe they went "a cheaper way" with the Rival since now they have a huge name in the gaming niche community, and are doing the same as what Razer did;
Build the name with very good product,
Become big,
Make sure to build a good fan-base,
Go with cheaper ways to lower the prices, increase the sale volume,
The fan-base will always be sellouts to the name they have been using for long.
If you really want to see some good Steelseries mice, you gotta go with older stuff, an Ikari for example, optical or laser. Even for the Sensei, i believe it feels super cheap. "Frying pan" in a nice way to describe its kindoff horrible feel.
Just like if you want some nice Razer stuff, go with the older models that are discontinued but might be on after-hand market (maybe you can find some factory new stuff!). I remember my old DeathAdder, it was flawless, incredibly good. When i tried the new edition, it really didn't feel the same as my old mouse. For some reason i felt it was a cheaped out mouse with the same shape. Couldn't get that "authentic" feel.
My friend bought an Ikari Laser off eBay, paid a third of the old MSRP, and is super happy with it. While i know it's a 150$ grade mouse and here we are talking about a 40-60$ one, i still think it's super sad that it has come to this.
While all of the above are definitly only some suppositions and hypothesis, i believe we can all agree that the more we are advancing, the cheaper everything gets manufactured, with cheaper stuff and cheaper cheap-labor. Especially with computer hardware, how low can it goes? isn't a 5$ keyboard cheap enough? Since most people don't repair their items anymore, people simply rebuy cheap stuff, sooner than ever before, and always go with the cheapest of their favorite sellout brands.
Razer understood it first, how puny of a joke the BWU is for a mechanical keyboard...
Same is going for SteelSeries... since when would a dumb "3D printable" nametag is a selling point...
It's bad, but luckily there's still some reals out there making stuff worth paying big bucks for.
