The timer, or the plastic housing makes a high quality impression. Very practical is the large display, what was the reason of purchase. The keys are well-sized and can be pressed well. It is also gratifying that the plug sits tight in the wall socket and also the Outlet of the unit is tight. The manual is understandable and programming the inputs and sleep timer simply. Up to 16 timer created and the different weekdays are allocated. The timer also switched according to the specifications, as you would expect. By randomly pressing the SET and CLEAR buttons appeared random, ie Shuffle set timer, the display on and press the PROG and CLEAR buttons, there is a Timer up to 99 hours and 99 minutes and then one off the connected equipment. Both are not listed in the manual. At least the timer have very useful for devices that do not have a sleeptimer function. Unfortunately, the first timer had scratches on the screen and was reclaimed from Amazon.
