The advantage with savings bonds is this, that when you buy it, you are sure of what rate of interest it will be earning, as the interest on bonds is fixed. On maturity, the investor will be sure of the return on their investments. The only issue is that the return is usually a small percentage and you stand to face fines if you decide you want to cash your bond easier than its maturity. Other than that it's a good investment.
