Works OK
Used as a limit switch and as a detector with a slotted disc to measure RPM. Functioned fine but I noticed that within the batch I received some of the optical components had been soldered on squint. Also it would have suited my application better if the pins had been on the reverse side of the board out of the way of the moving part that had to pass between the optical slot.

Perfect as filament-out switch on 3D printer. Robust construction.
General purpose opto-switch perfect replacement for the stiff old mechanical microswitch on my 3D printer. I bought a pack of five, fully expecting to damage a few of them during development but they are actually very robust and I need't have worried. Great little device.
