K.W.
I haven't tried the new ones with timers, but I've been using crockpots for years! I would suggest if you aren't sure when you'll be home or you'll be gone at least 10 hours, try a large roast, chicken or pork...or some soup. There are really very few recipes that would be worse if cooked too long. That's the beauty of it! Remember, crockpots are slow heating and not as high as other appliances...that's why you can leave them all day. I've never had a problem with mine. If you need recipes, try www.crockpot.com. Or, I'd be happy to send you (or anyone) some; just email! ____@____.com
