I bought the Abyxolute S9 Type C controller. The shipment was very fast and the package was nice. The controller works as expected and is a very good match for my Lenovo Y700 tablet.
The main positive point is the comfort. It's pleasant to use, even for longer sessions. The size is good—it's not heavy and it feels comfortable in the hands.
The build quality seems fine. The buttons are responsive and the triggers feel nice. Overall, it's a good controller. If you're looking for a comfortable and reliable option, especially for a tablet like the Y700, the Abyxolute S9 is worth considering.
