Rating : - The Intermatic Death Curse
Like several other reviewers' units, mine worked fine for a couple of years, then just died. The numbers kept ticking, but the on/off just stopped functioning. Same fate as two earlier models of Intermatic built-in wall-switch timers. My advice - divide the product price by 18 to 24 months to get your per-month cost. If it seems steep, try another brand.
