    Every one of them works. It does what it suppose to do. Which is give 0/1 (True/False) when it detect object. This isn't range finder. It will only response when there's an object in front of it at the set distance set screw on the unit. It doesn't come with the wire as in the picture above.

    Average to good quality and very usefull in building robots that need avoiding obstacle. They have all of them a small error on soldered pins (see the pictures). But this is a quite small manufacturing error that will not affect functionality.

    Handy ready made Sensors. Would cost me more to make then BangGood offer's these for. Going to be used on my Wind Power Turbine project as a Tachometer Sensor. I just need to Remove and Relocate the IR Tx and Rx diode and Transistor. Thank You BangGood.

    Stick 'em in front of your robot car and have fun. They are simple little devices, but can help a lot with your project.
