Good construction and easy to modify
I bought 20 of these to interface a Nayex credit card reader to a car wash. The card reader would output a 5V signal and the car wash required pulling a 12 volt line to ground. To make it reliable, I had to replace the input resistor with a smaller value. I think it was a 1k and I replaced it with a 220 ohm resistor. The resistor value needed depends on the output current required. I expected I'd need to modify it when I bought it. It was easy to modify and all 20 of them have been working perfectly for a year now.

Perfect circuit isolation
I have no complains at all. The item is entirely as described.

They both worked as expected. - but not PC817
They both worked as expected. The reason I gave only 4 stars is becasue the chip is a TLP785; not a PC817 as the mistakenly statr in thier product description.

Works well after figuring out instructions
The instructions are a bit confusing if you're not familiar with the terminology, but after figuring it out it's worked quite well!

Did the job
No issues with these

Not good for Arduino switch
On 4V input there is 90+ Ohms resistance between GND and OUT, 8V has 38+ ohms and 13V has 29 ohms. This is very significant as I tried to switch LED array and they were not as bright as using relays as switch.

screw terminals rusted
both of them had rusted screw terminals right out of the box

Specifications wrong
Datasheet for a PC817 doesn't match this optocoupler, which is for a TLP785.
