I was using an old reciprocating saw that required an allen wrench to insert & remove blades. This saw has a quick lever to insert & remove blades effortlessly. It also has a rotating head.
This product, like Sears in general, is junk. I only bought it because it was specifically requested as a gift. It is no wonder Sears is going down the tubes.
12 Amp is plenty strong enough for any remodeling project. Happy with purchase.
