Just recvd it in the mail and gave it a run through the paces. Came UPS, well packaged and time pre-set for Arizona time. I spent a couple days shopping for a timer that would do what this one claims to do to no avail. The timers I found were priced within $5.00 of this unit and would not do the simple countdown feature. Instructions and operation is straight forward!! Unit will do what they say and much more. They are on sale right now for $19.95 which may sound a little much at first, but when you can set your tumbler to run for 2 hours 47 mins. and go do what ever knowing it will shut off it, is worth it in my book.
