If you plan on using this remote with a wall switch, when the wall switch is turned off, and then back on, the remote defaults back to 'off' position, therefore, you will need to hunt down the remote in the dark to turn the lights back on, as opposed to the remote maintaining the settings at the time the wall switch was turned off.
My other, more expensive, remotes DO remember the last setting when the wall switch is turned off making the wall switch useful.
In summary, this unit is fine if you plan on NOT using a wall switch with it.
