It's a good tool, just don't overuse it. Make sure you train the bottom end too(long pauses, pin press, spoto press, etc.). I actually find that benching against bands gives a better training effect because it forces you to keep accelerating the bar, whereas the slingshot accelerates the bar for you. The downside of bands is that they are hard on your joints, so you don't want to use them too often. Both are good for raw lifters, but they should not be the staples of your program.
