I haven't had an opportunity to actually put it into real life use just yet(drilling into concrete). Just by the feel, I can't feel much power. The price was pretty high, especially given it's not a name brand hammer drill. However, seeing I haven't truly tested it in a real life scenario, I can't truthfully say whether it's work it or not. Walmart does have some of the best warranties out there. Which personally gave me the confidence in purchasing this product. Which is the only reason I'd recommend this unknown product to another. Once I use it, I'll do my best to give a more rounded review.
