From Fed Chairman Ben Bernanke at the Jackson Hole Economic Symposium: Monetary Policy since the Onset of the Crisis

The potential benefit of policy action, of course, is the possibility of better economic outcomes--outcomes more consistent with the FOMC's dual mandate. In light of the evidence I discussed, it appears reasonable to conclude that nontraditional policy tools have been and can continue to be effective in providing financial accommodation, though we are less certain about the magnitude and persistence of these effects than we are about those of more-traditional policies.
...
In sum, both the benefits and costs of nontraditional monetary policies are uncertain; in all likelihood, they will also vary over time, depending on factors such as the state of the economy and financial markets and the extent of prior Federal Reserve asset purchases. Moreover, nontraditional policies have potential costs that may be less relevant for traditional policies. For these reasons, the hurdle for using nontraditional policies should be higher than for traditional policies. At the same time, the costs of nontraditional policies, when considered carefully, appear manageable, implying that we should not rule out the further use of such policies if economic conditions warrant.
...
the economic situation is obviously far from satisfactory.

Early in my tenure as a member of the Board of Governors, I gave a speech that considered options for monetary policy when the short-term policy interest rate is close to its effective lower bound. I was reacting to common assertions at the time that monetary policymakers would be "out of ammunition" as the federal funds rate came closer to zero. I argued that, to the contrary, policy could still be effective near the lower bound. Now, with several years of experience with nontraditional policies both in the United States and in other advanced economies, we know more about how such policies work. It seems clear, based on this experience, that such policies can be effective, and that, in their absence, the 2007-09 recession would have been deeper and the current recovery would have been slower than has actually occurred.

As I have discussed today, it is also true that nontraditional policies are relatively more difficult to apply, at least given the present state of our knowledge. Estimates of the effects of nontraditional policies on economic activity and inflation are uncertain, and the use of nontraditional policies involves costs beyond those generally associated with more-standard policies. Consequently, the bar for the use of nontraditional policies is higher than for traditional policies. In addition, in the present context, nontraditional policies share the limitations of monetary policy more generally: Monetary policy cannot achieve by itself what a broader and more balanced set of economic policies might achieve; in particular, it cannot neutralize the fiscal and financial risks that the country faces. It certainly cannot fine-tune economic outcomes.

As we assess the benefits and costs of alternative policy approaches, though, we must not lose sight of the daunting economic challenges that confront our nation. The stagnation of the labor market in particular is a grave concern not only because of the enormous suffering and waste of human talent it entails, but also because persistently high levels of unemployment will wreak structural damage on our economy that could last for many years.

Over the past five years, the Federal Reserve has acted to support economic growth and foster job creation, and it is important to achieve further progress, particularly in the labor market. Taking due account of the uncertainties and limits of its policy tools, the Federal Reserve will provide additional policy accommodation as needed to promote a stronger economic recovery and sustained improvement in labor market conditions in a context of price stability.

QE has been effective and costs appear manageable.
