I don't expect them to be used for anything critical, but they should be useful for things like automatic cat doors connected to the internet. The action seems very positive and satisfying. Build quality isn't great but function is all I care about and the very low cost has to be factored into expectations. I'd like to do a proper resistance test, but that requires a bit of tweaking if you don't have a real milliohm meter. I will edit this review as and when I get around to it. Note the difference between the maximum AC and DC current ratings. As almost always, the DC rating is MUCH lower than AC. This is quite normal and to be expected. Don't expect regular mail from Asia, get it from a US sender like this one.
