Just works
OK, "just works" is a slight exaggeration.
I plugged this in, turned the TV on, went into network settings, selected wifi settings, picked the right network, entered the password and it was done.
The instructions provided with it were for use as a computer dongle. A quick instruction sheet might be nice for the less confident, but most people will find it easy enough.
I haven't used it for any length of time, so I can't comment on reliability.
