Reliable compared to what?
Why would you expect them to be reliable?
How much testing do you think has been done on these things?
Do you think the designs have all had 3rd-party review by qualified engineers?
What do you think the reliability is going to be with minimal testing and no serious checking of engineering?

Think it through and you'll see what happens...
