I use about 4 sets of these throughout the house/garage. They are reliable, convient and do, overall save money.
They control the following,
Lights
AV equip inc sky etc
TVs
Computers
Battery chargers
video senders (instead of using fiddly switches)
Have checked these against my power usage meter (only got it this weekend) and if I switch the plugs off via these instead of going into standby my usage drops from 0.27 to 0.15.
now and again they do switch off randomly, but that was down to confliction with a nieghbours new set, so I switched channels, re-learnt and no issues since.
The greatest use is seeing the power meter running higher than normal when I have already gone to bed and then doing an all off without getting up - now just need to combine into either 1 remote or control by computer - any ideas on this would be cool.
hope that helps
