Query: Does not shut off

Waste of money, just like all Menlor products. I've bought 5 different Menlor/Vigoro timers and all 5 have failed within 2 years. I'm the fool for buying them, but I won't anymore. It's convenient to get them from Home Depot, but I'll never make that mistake again. This particular model failed right out of the package. The on/off switch would not shut off.
