Happy customer
Good quality. Exactly what I needed

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.

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

Current set well below chip specs
it's not PC817 as advertised, but TLP785G, which is actually a slightly better part. The problem is in the choice of the input resistor: at 4.7 kOhm, it only allows ~2.2 mA at 12V, resulting in ~3.5 mA output current. This is plenty enough to drive an MCU input, but may not be enough for other loads, and far below the capability of the chip (60 mA max). The recommended input current for TLP78 is 16...25 mA, so the input resistor R1, which is 4.7k, should be considerably smaller, perhaps ~680 Ohms, if higher output current is needed. The seller would do their customers a favor clarifying this.

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.
