The first one I bought looked like it was in use. It was dirty and packed in an unmarked box with an odd seal. I sent it back and opted for a replacement. I'm sending replacements back now. Daily random switching of programmed sockets with "Auto On" to "Automatic off". So what you expected to stay on - turns off! It's "F", so come back. It's a pure roll of the dice what you get. The company clearly lacks quality control to prevent inferior products from reaching consumers.
