Review on 4pcs 3D Wireless Thumb Sticks Sensor Replacement for Xbox 1 and PS4 Controller - Onyehn (4 Pack) by Samantha Carlisle

TLDR They work but are clumsy and not as sensitive as OEM joysticks. Only buy if you need to replace the pads in an OEM joystick. Long version. These joystick sensors are not as sensitive as OEM sensors. I read some other reviews of these sensors after purchasing them and realized that instead of soldering, they just replaced the pads in the OEM sensors. If that's all you need to do, find one of these sensors which is the cheapest as they perform about the same. However, if you are doing a full sensor replacement, I would strongly advise against buying them. Their movement and weight feel chunkier and heavier than the OEM sensor, and after checking the sensor's accuracy with a utility tool, they're nowhere near as accurate as the OEM sensor. Installing the sensor wasn't difficult for those who know how to solder, but it wouldn't be accessible or convenient for everyone. I give them two stars because they work, but they are not good replacements for OEM joysticks.
