Durable
This is a really good quality controller, its about the same size of the orignal controller, feels comfortable and really durable. Im aggressive with my controllers and surprisingly nothing is going wrong with it. Had it for like a year now and working perfectly fine. It does have it issues with staying connected when you first turn it on, but when its connected and working it doesnt cut out.

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.

A good controller
The controller lived up to my expectations; it’s very comfortable to use, looks great and is easy to operate, and is compatible with games on all the platforms I’ve tried without needing to install anything extra. The cable it comes with is quite long and flexible.

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.

One design flaw, otherwise EXCELLENT!
This is an excellent controller with one design flaw. The 'View' button (between the left Joy Stick and center X Box button) is set too high and difficult to press in a hurry because the left Joy Stick is in the way. The 'Menu' button is similarly positioned, but one must only get used to it being much higher than on a Microsoft controller. It is otherwise unobstructed. There are subtle differences in the feel of the buttons and joy sticks from a genuine Microsoft controller, but only OCD people like me care about that. I chose to up my joystick sensitivity one notch in games to account for it. ABXY button presses are a fraction of a millimeter longer. I'm sure I'll get used to it. Otherwise, it's great and comes with a long superb cable.

Stick drift no more!
I can’t count how many Xbox controllers I’ve gone through. I buy them for $70 and they get stick drift within 3 months or the buttons decide to not accept input the first few times u hit it. I’m not even a huge gamer then I buy this for 40 bucks and get a controller than not only feels higher quality but the latency is non-existent and it still holds strong years after buying it. Looks cool af too

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.

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.
