I'm wondering how long ago you bought yours and and how much it cost. I paid $20 at Menard's.

Here's my working hypothesis: to get the price down and appeal to a larger market, the newer model (4400.01) uses cheaper components with larger tolerances.

Don, would you please compare the label on the back of your unit to this and note any differences?

Also, could you try your unit with a 60W incandescent bulb and tell us what the Watt readout says?
