Great feeling controller
This controller feels good in your hands and the weight is nice. It holds a good charge and charges easily. I have used on my phone, tablet, and pc with no lag issues. No stick drift and excellent response. I like the triggers on this controller they bounce back quick and don’t feel squishy. Has extra buttons for mapping and other things. Just as good as some very expensive ones I’ve used. Great all around controller!

Quality build
I didn’t expect to get Hall effect thumb sticks but after doing some circularity tests and opening it up this did come with them. Have been using this for Fortnite, slippi melee and apex. I will say that the dpad is very sensitive and may give neighboring direction so buttons a misinput. The joystick toggle press in is way more sensitive than a stock Xbox controller and has been messing me up at times. The biggest adjustment is just how fast this controller is. With 700-1000 hz polling rates and 1 ms response time it’s the fastest controller I’ve ever used. With Fortnite specifically I have to get used to the inputs I use otherwise I mess up my editing sequences. Will take a second to get used to even if it mirrors my default Xbox controller with 4 button strike pack attached. Also I purposely bought the version that I thought didn’t have Hall effect thumb sticks bc I’ve had other controllers with he thumb sticks and my fine tuned aim and flick shots are tailored to the standard 12%-18% error rate that I experience on the corners of stock Xbox controller thumb sticks. If anyone knows of a way using possibility 3rd party software to simulate that error rate that would be awesome m. Message it to my gamer insta saruno

Could be an excellent controller for the price, some caveats.
This controller has several things going for it, and maybe just a couple not. I like (and is the primary reason I made the purchase) the FOUR rear buttons. There are many controllers these days with rear buttons, the vast majority of them seemingly have two. Which would probably be amazing for someone that’s never had them before, but all my controllers either have 4 or can install 4 total. I may not always use them all, but even if I’m just using two sometimes I like for them to be on the same side, I enjoy having that configuration flexibility. The rear buttons of this controller are in a slightly odd position for my hands, I wish they could have been closer to the bottom of the grips, but it’s a minor adjustment. I do like that the buttons are placed vertically and not some other nonsensical configuration. I like that there is no rubber coating on the body, the grip texture on the back is actually a fine pattern of micro bumps molded into the plastic. Felt a little strange at first, but I find myself liking it a lot the more I use it. The face buttons feel good, the Hall triggers feel really good, the sticks (once I put some covers on them) feel good although I wish they had Hall sensors like the triggers. I have mixed feelings of the bumpers, they’re positioned well and are easy enough to operate, but I don’t like the click and how loud they are. Not a deal breaker to me, but I do wish the actuation was softer. I don’t particularly care for the gyro function, but it was never my intent to use it anyway. I tested the gyro briefly, mostly by accident, one of the rear buttons is configured by default to activate the gyro. It mentions this in the instructions, but I guess I still wasn’t really expecting it. Basically like all motions controls, it sort of “works,” but is mostly a flaky and useless gimmick. I’d have preferred to lose the gyro and gain Hall sticks, but such is life. The D-pad feels good to me, probably about as good as the face buttons. I don’t know how well it would do with a fighting game, I haven’t really played those in decades, but for my purposes it works fine. I probably wouldn’t use a controller like this for a fighting game anyway, I’d prefer something shaped more like a classic SEGA 6-button or a SNES pad.The hardest part of operating this controller was actually finding a device that the configuration software would work with. I started with my phone, which has a MediaTek chipset. The KeyLinker software mentions at startup that it may not work correctly with MTK hardware. The app was able to detect the controller, but could not actually interface with it. Fortunately, I have other devices to test with, so YMMV. Took a few tries, but I did eventually wind up connecting it to a device that worked, a Galaxy S7. Once up and running, the configuration software worked great. My controller was already running the newest available firmware. The app has an advanced mode which gives more granular control over the various options, especially the deadzones. There are sections for key binding and macro management, although the controller itself is able to do some things like rebindings directly. After a few minutes of testing I’d had my sticks and triggers adjusted perfectly, was even able to set a custom sleep timer.The controller comes with a detachable phone holder, it seems pretty sturdy to me, although my phone is quite small and very light anyway. There’s a cover around the USB port that slides off to expose the attachment point for the phone holder.I haven’t had any connection issues. Aside from the mobile app quirks, but the connections were fine, my issue was finding a device the app worked correctly on. I have no Switch to test the Switch connection. I’ve been using it with an Xbox One, connected through a Brook Wingman XB by bluetooth. The wireless dongle it comes with also seems to work fine, to get that to work correctly with the Wingman it had to be in XInput mode. Switch Pro mode mostly worked, although the triggers were digital. DirectInput mode did not appear to be compatible with the Wingman.For the price I paid, and considering the features they managed to stuff in, I think this is a really nice controller. Maybe not as nice as my collection of PowerA Fusions, or Xbox Elite, but it’s half the price or less compared to some other devices. As is, I think the controller is a good value. If you have a device that can run the companion app correctly and are able to calibrate the controller, it’s a VERY good value.
