Probably the best third party Xbox controller for PC!
These are good controllers, solving both the longstanding problem of micrometer stick drift via Hall, and my previous problem with the prior release T4 Kaleid of confusing firmware options conflicting with PC settings (they came default shipped with Nintendo firmware setting active, which is solved by button press combinations to be fair, but this took me an embarrasingly long time to figure out) I don't know if the Kaleid Flux multiple firmware options for other consoles but as I'm 100% a Windows PC gamer it's the best fit for me. They also have a longer braided cable than the T4 which I appreciate as I roll over them with my office chair or get entangled in it etc. I like the black aesthetic and the damascus style printing on the circuit board. My prior T4 did develop one of the usual problems with hard use of the left trigger cutting through the internal conductive rubber so the button stopped working, but that's been a thing with multiple brands of these controllers for a long time vs. my grip strength and nerd rage at some high APM titles so we'll see if this one holds up better. This is the second Kaleid Flux I bought and for a second player this time instead of a replacement after months of controllers from other brands failing on me so I do believe GameSir is the best third party manufacturer at this time, and better than native massively overpriced Xbox controllers to boot. Good job GameSir!

Very good quality
Feels like good quality and the month of game pass is a really nice addition and adds to the value of the controller. It also comes with a couple accessories like a microfiber and stickers. Nothing crazy just nice to have. Overall a really nice controller and the lights looks much better IRL than the pictures show.

Premium build! Love it!!!
I never thought that I would go back to a wired controller, but I play call of duty pretty competitively and I got tired of the lag, so I decided to give the Gamesir Kaleid Flux a try, and i’m so glad I did. I’m in love with this controller. The build quality is excellent to me. It doesn’t feel cheap. It feels premium. It has a good weight to it, (not to heavy, not to light) I love the way it looks and feels. I find myself grabbing this controller over my regular wireless Xbox series X controller constantly. It took like 10 minutes to get used to the barely smaller size than the regular Xbox controller but other than that, I have no complaints at all. The lights are cool. The app is really easy to download on your Xbox to update your firmware of the controller, which I didn’t have to update mine, it was already up-to-date, but you can set profiles on the app and everything to remap buttons, vibration, whatever you need I looked through so many wired controllers, and this one always popped up. I watched countless videos and reviews of this controller, I decided to try it and you should too. This controller is awesome. It really has me playing call of duty and Fortnite like a pro. I did do a little bit of collaboration in the app. I didn’t really change any buttons and I don’t use the back buttons, but I did switch the triggers to hair trigger, (I’m pretty sure that’s spelled wrong) and mess with the thumb sticks a little bit, but that’s just personal preference. The controller is plug and play right out of the box which is how I first used it to test it out. You can also change the colors of the lights in the app, as well as turn them off, brighten or dim them, and change the speed of the movement or you can have solid colors with no movement. If you were looking for a premium solid wired, Xbox or PC controller I definitely 100% recommend the Gamesir Kaleid Flux.

Very good at, um, controlling games
Some people might buy this controller because it's largely translucent and has RGB support and generally looks pretty cool. Those people will like the way it looks out of the box and on default settings. I'm not one of those people. They will find that the GameSir app on Xbox lets you tweak the colors extensively and gives really fine detail control of the colors and the flows and all that. For me, it wasn't worth the time it would've taken to dial in my own super color motif. I didn't like the app, it wasn't intuitive and I wasn't invested. If you are, I'm sure you can figure it out and get a result you like. I bought this for the Hall joysticks and remappable extra buttons on the back. These features are all pure win. Controller feels good, works good, plays good. It has the drawbacks of needing to be wired and feeling really light compared to anything that holds batteries onboard. For some, this may feel cheap or fragile. The plastics seem to be thick and high quality enough that an unexpected breakage seems unlikely. If you play Mortal Kombat or haven't had a Victory Royale in a while, you can probably still bash it to death after a frustrating loss but the controller won't make it easy for you. I like this one a lot. Does exactly what it says and works great doing it. It might be my own head cannon, but I do feel like I have better fine control that say a stock Series X controller.

Great controller unless...
Great controller. Every works the way it is supposed to. My problem is needed the a longer cable than the one the came with it. So I plugged a longer c cable and the controller has no power. Tried an extender still no power. So I f you need a longer reach than ten feet don't bother with this contlloer..

Honest opinion
I got this controller because gamesir advertised it can't get stickdrift due to the magnetic technology. I haven't had it long enough to know for certain but I do enjoy the back pedals, and everything is clicky and responsive and works good. I like the braided cord. It makes it feel more durable. Though I have cats so we'll see how that fairs. Overall I really like it and think it was worth the price. And to be clear it's roughly the same here as the "sales" are on Tiktok, but here you can get it sooner.

Great Controller… Until It Breaks. Support Is a Nightmare
I really wanted to love the GameSir Kaleid Flux. For the first couple of months, it worked beautifully—responsive sticks, great triggers, and a solid feel overall. Unfortunately, the honeymoon ended fast. The directional pad stopped working, and the audio cut out shortly after. I reached out to GameSir support, and that’s where things went downhill. They asked for multiple videos of me troubleshooting the issue, which I provided. Eventually they told me a replacement would be shipped via USPS. A tracking number was created… and that’s where the process stalled. USPS showed “label created, awaiting item” for weeks. I contacted GameSir again, and instead of resolving the issue, they restarted the entire process. This has been going on for a month, and I still have no replacement and no real progress. The controller is good while it works, but the support experience has been incredibly frustrating. If you’re considering this product, just know that if something goes wrong, you may be on your own.

Bottom line: upfront, highly recommended. Get this if you are in the market for a gaming controller for your PC. Straight out of the box, this controller felt like quality. The box itself was very purposely made with lots of thoughtful features. It was one of those boxes, you want to keep because it’s so nice. The design and light functions are very nice and classy. I was impressed with the light functions as they kept with the actual design of the controller. Having more buttons available than I need was very helpful in configuring my button layout for multiple games. Not all games require the same buttons in the same places, and this one allowed for programming. This controller's feedback or rumble feature is perfect, not too much, not too little, but also has adjustments in case you want it more or less, or even just off. The button response is as expected and can be adjusted. The USB-C cable that comes with it is sturdy, robust, and made of high-quality materials. I’m glad it didn’t come with a short cable like some of the other controllers. This cable was just the right size. The instructions that come with it are in 11 different languages, so I think they cover most of the basics. And the final touch is the free sticker they give. I could never have enough stickers.

No stick drift!!
Brilliant. Had no issues with stick drift since purchasing this item several months ago and used on a daily basis. Love the different colours too.

ボタンは静音で反応良し。線の硬さは気になる
機能的には問題なく、ボタンが静音で素晴らしいです 標準のコード(タイプC)が硬いのが難点で、他のコードに変えようとすると似合わなかったり穴に入らなかったりする 線の硬さは普通のプレイヤーならそこまで気にならないかもしれませんが、頻繁に持ち替える開発者だと少し気になるといった感じ

Un control que ofrece calidad a un costo bastante accesible
Un excelente producto, el plástico tal vez no se sienta tan premium pero si resistente y bueno para lo que ofrece, solo me ha dado algunos problemas con las luces a veces, pero en si de ahí todo está perfecto, el cabe de buen tamaño y realmente si se siente de calidad, el control es demasiado ligero, y es una ventaja yo creo, tal vez la vibración no es muy fuerte como me gustaría, pero se siente demasiado bien, realmente si lo recomiendo, leyendo el manual y los comando que trae, es un 10/10

Perfect. Just as good as the G7 SE with the added perk of RGB lighting. Everything you want in a controller. Custom back button, responsive sticks and triggers and if it goes the same as the G7 SE I've had for 10 months NO STICK DRIFT. There is no negative to this controller.
