- Reviewed in Canada on May 15, 2025Verified PurchaseIgnore all the reviews that complain about the size of the product, it's almost the same size as the regular controller. It has neat features, I really like the paddles in the back and being able to use push to talk with the microphone as well as being able to quickly remap the back paddles to any button on the fly. The sticks are just as sensitive as the original controller but no drift! Also no center dead spot. Makes fine tuning aiming much easier. I'm a pro MLG player and this is now my go-to controller. The only bad thing about it is that it's wired, but so is my headset and it's never cut out on me halfway through a gaming session. The cable that comes with it is stiff but sturdy and very long. I like the hair trigger function, I just wish I could change the color of the led when I press it. Also it's much more comfortable in my hands on long gaming sessions. I just can't say enough about this thing. Buy two of them and give one to a friend and see if they like it.

- Reviewed in Canada on November 2, 2024Verified PurchasePros: Very comfortable shape as it is slightly bigger than G7 SE/HE, much more silent left and right triggers compared to the SE/HE with no pinging, better rumble than SE/HE especially when it comes to the grip vibration, excellent hall effect sticks, better QC standards than the SE/HE in my experience, great face buttons that register properly all the time unlike the Microsoft-brand controllers, beautiful braided cable, even the Gamesir Nexus software works properly with it and exhibits no glitches.
Cons: Nothing really significant to speak of. Minor things that theoretically could be improved would be to make it wireless and have rubberized handles.
Conclusion: Gamesir hits it out of the park with this release. After going through a few HE/SE G7 controllers with various QC issues, my first Kaleid Flux is a winner. I did keep one G7 HE as a spare because of its rubberized grip and great clicky face buttons. In a direct comparison though, I would ALWAYS pick Kaleid for me because of its larger size including thicker handles and more consistent build quality where all the buttons and triggers have a more uniform feel. It just feels like a more polished and finished product to me. Oh, and it has amazing LED lights if that is your thing.
Update: Took off one star because of the following : After a few days of using it, I discovered the first bug that is not necessarily a deal breaker, but is annoying. If you have the default LED lighting profile enabled, it appears that something triggers a "ghost input" where either the "A" button or "L4" paddle gets pressed without any input by the user.
I discovered this after leaving my XBOX turned on in main menu for a few minutes and then coming back to a game running, as if I had pressed the "A" button. From my limited research on this matter, I have seen other users report this and they tie it to a combination of LED lights being turned somehow activating whatever keypress is mapped to L4, left paddle. I have the "A" button mapped to this paddle.
I really hope Gamesir can address this with a firmware update. I don't really care about LED lights that much, but one should be able to use them.
- Reviewed in Canada on October 7, 2024Verified PurchaseI just want a controller with Hall effect so it will last a little longer and save the environment. This looked passable if a bit flashy/gaudy, since it advertised hall effect. Right out of the box it feels like a dollar store tier plastic, not worth $50-60 already. I plug it in and nothing. It lights up and does a fancy LED light show but zero functionality in any games. Steam wont recognize it. My OS's controller config tool shows zero inputs. I tried diff drivers, I tried a different OS on a live-usb, nothing.
The one thing it's supposed to do - be a controller for games - it fails to deliver on. Refunded and returned.
I'm still stuck using my old broken controller with duct tape over the back buttons because I can not find a simple reasonably priced good quality hall effect controller. Also the brand name is so cringe i'm kind of glad i didn't keep it, gamesir ew who came up with that. Yeeesh.
- Reviewed in Canada on May 29, 2025Verified PurchaseReally nice and sturdy controller.
- Reviewed in Canada on November 9, 2024Verified PurchaseSo, I looked for a new controller as the one I had started getting some drift. Long story short, I stumbled upon this and actually got worried about the reviews. Maybe the worrisome reviews were random because I haven't had any issues yet. I purchased this for BO6 and I can tell you, the sticks have stayed at 0% since I got the product. The sticks actually feel better, they don't feel so "sticky" after awhile. The software is easy to use, just needs to be googled and installed. The lighting is cool but honestly not needed. If you're looking for a new upgrade, I would highly recommend trying this out or any other hall effect type controller on the market.
Side note, the package included a trial for game pass (which I didn't expect so I gave the code to my brother)
Anyhow, expectations are different from person to person so, make it your own decision to try it out.
- Reviewed in Canada on March 29, 2025Verified PurchaseWorks pretty good. Only have two concerns. 1 the buttons under are not in a good spot. Maybe my hands are too big but when I pick it up I hit those buttons by accident. When I'm playing I hit those buttons, so they go unprogramed. Being move up and more in centered would help.
2nd. The d pad always clicks up when I press the left or right on the d pad. Have to force my way of thinking by clicking down right or down left to get a right or left click.

There is an app to download, where you can customize colors, buttons and whatnot
Great price, overall pleased with purchase.
Purchased as my original Xbox One X controller developed stick drift, took a bit to get used to as the buttons arent exactly where they are on original (the screenshot button to be clear) I like it so far, havent tried the buttons on bottom as I mainly play Fortnite zb. I chose this model as I was tired of my batteries dying mid match, only complaint I have is that my amp for headset cannot plug in now.

Sali muy bien el control, se siente la calidad, si lo recomiendo xdReviewed in Mexico on May 13, 2025
5.0 out of 5 stars Un control que ofrece calidad a un costo bastante accesible
Verified PurchaseUn excelente producto, el plstico 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 ah todo est perfecto, el cabe de buen tama?o y realmente si se siente de calidad, el control es demasiado ligero, y es una ventaja yo creo, tal vez la vibracin no es muy fuerte como me gustara, pero se siente demasiado bien, realmente si lo recomiendo, leyendo el manual y los comando que trae, es un 10/10

5.0 out of 5 stars Flawless
Verified PurchasePerfect. 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.

5.0 out of 5 stars Beautiful Controller
Verified PurchaseWhen my cheapo Xbox one controller let go I knew I needed to go big. The second I saw this controller in a review video I just knew I had to buy it. This controller combines quality, comfort, tech, and amazing looks all into one very affordable product. My friends are always amazed at how good my controller looks, especially with the lights on!
For everyone wondering about stick drifts and the potential of them feeling weird because they're hall sensors, you will never notice the difference unless you are huge into controllers. Expect to never have drift again and an amazing experience with the peace of mind.
