Your review: If you are installing this for someone like a senior citizen who wants something w/ ease of operation, I recommend this unit.
Pros: This is a great unit in that it is not complicated at all. It does what you want it to unlike some other more complicated units where if things are not working correctly, you are not sure if the problem is the unit or you. This thing just works! And if it doesn't you know it and you just replace it at low cost.
Cons: Cannot program it for times of day. This may not be important.
