Is Procter & Gamble (PG) - Get Report a good long-term investment?-- Tim from Detroit

Jim Cramer

: Yes, I do think Procter is a good name for the long term, and I own the stock for my charitable trust

Action Alerts PLUS.

I believe that Procter has the best lineup of brands of any consumer products company in the world. The company's recent merger with Gillette also gave Procter an incredible lineup of men's care products.

In addition, Procter should do well during economic downturns, because people don't stop shaving and using toothpaste even when times are tough.
