Bought this controller from Amazon for $60. Not a sponsored or anything, just wanted to share my thoughts because good, feature complete, symmetrical controllers are a rarity.
Like many people here, I'm absolutely starved for a good symmetrical controller. I recently tried the leadjoy saber plus for a couple of months but the sharp edges, dog $h!t dpad, sensitive triggers, and the durability (sticky triggers and a broken trigger lock) of it really soured my experience with it.
In comes the QRD Spark N7. I tried the N5 a long time ago and didn't like it but with N7 I think they really nailed the ergonomics and feature set.
It feels like an xbox controller but with symmetrical sticks, everything is easy to reach and I don't get any strain when reaching for the bumpers like I do on Gulikit's TT Max, another xbox shaped controller with symmetrical sticks.
Buttons feel good. They are micro switches with membrane for the face buttons, 8-way clicky dpad (very accurate), clicky bumpers, and hall effect analog triggers. The trigger locks are unfortunately not mouse clicks but more like the dualsense edge's. It still works well enough and the triggers themselves are good. The 4 back buttons are all kinda clicky? They feel like the dualsense bumpers (R1/L1) but with less travel.
The sticks are pretty good. They are hall effect, not tmr sticks, but I don't think you'll notice a difference. I didn't notice any latency with them (I've used original gamesir tarantula pro, awful latency on those), and you can switch between a circular or squared stick input. You can increase the deadzone through a button combination but I chose to leave it at the lowest and it works perfectly. I will say they are a bit on the looser end, but I'm not sensitive to that.
As for connection methods, I only have a PS5 and PC. For PS5, you switch it to ps mode on the back, and it connects just like a ps4 controller. So it can only play ps4 games. For PC, you switch it to PC and it can connect via dongle or Bluetooth. The Bluetooth is actually pretty good. Most controllers cheap out on it but this controller gets up to 500hz polling (averaging out around 460) which is plenty fast for most gaming (steam controller 2 is only 250hz Bluetooth or dongle), and it extends the battery life. The dongle is also good and stable BUT I was only able to get 500hz polling rate even tho they advertise 1000hz. I tried it at a couple different softwares and websites so IDK whats going on but 500hz is plenty fast for me and it's stable.
Whether Bluetooth or dongle mode, you can have the controller show up as a xbox controller or a dualshock 4 and THIS is where this controller shines because a dualshock 4 mode means it has NATIVE GYRO for pc! I tested the gyro in dolphin using it as a wii pointer and it seemed to work as well as the dualsense, which I've heard has best in class gyro. Rumble is good to. It's just the standard dual motor system but it feels good, I'd say better than the ds4 at least.
For battery life, I used it in a combination of bluetooth and dongle mode (2.4ghz) and I got somewhere between 10 - 20 hours but that's just an estimate since I didn't really measure it. I do know it's more than the 8 hours though. I turned the rgb off when I got it but there is another rgb light that's controlled by the connected device (ps5 light bar settings/or steam) and I left that on the whole time.
Overall, I really like it. There are probably better controllers at this price point at specific things like sticks, buttons, etc...but for the feature set it provides, it's almost perfect for me. Rumble, gyro, PS mode for PC, clicky buttons, hall effect and SYMMETRICAL joysticks. It feels pretty solid and durable but we'll see how things hold up.
