These switches have been working great for a little over two weeks with both an automatic (open-zwave schedule) and manual configuration.
Installation instructions are included. The only problem I had during installation was fitting everything back in the wall box as the switches are bigger than the standard switches they replaced.
The switches do make a loud click when activated. I have seen in other reviews that this is normal.
I paid a little under $20.00 per switch delivered.
UPDATE: I upload my hacked Z-wave controller code to: https://github.com/tagroup/open-zwave-tcp-socket-server-and-client
