Query: Works fine, no surprises

I've had it a few weeks, and everything has worked as expected. The power save and commercial advance features are very useful, and work as advertised. Minor disappointments are that only 8 programs can be set up, and the programming interface could be better. For example, I could easily enter the program time using the number keys (1-2-3-0 for 12:30, for example), but instead I must use the up and down arrows, slowly advancing from 01 to 30.
