Very Very light controllers, they work as described but they are cheaply made, I wish i just bought used xbox controllers instead.
Ordered 2 for my Raspberry Pi 4. Recognized as TGZ Controller. Wireless connection is mostly stable if there are no obstructions. Feels a bit cheap-in-hand, but button presses are decently solid. No rumble. Comfortable heft after inserting 2xAA batteries. All inputs work well after mapping, except for Home/Back/List. Printing is a little shoddy, e.g., see X & Y button quality in the last photo. Also, 1 of the 2 controllers I received is defective. As seen in the photos, the Right analog stick came tilted to the North/East by 2~3mm, causing drifting character/camera movements in a few games. One of the controllers also has very dim LED indicators for some reason. Overall, decent product at a decent price, with some quality control issues. However, the seller agreed to ship out a new unit to replace the defective one after messaging them about the issue. Kudos for good service! Would recommend buying.
