Query: Warning -- Limited Functionality

This product is awfully confusing to program -- you'll need somebody with a degree in science to figure out how to program it. Once you figure it out however, you'll soon realize that the worst feature is, the manual program mode allows you to set four different times, but only one can run at a time. So if you want to run your lights from 6am to 9am, and then from 7pm to 11pm, you can't -- only can run one of those times. This is a highly complex piece of junk.
