I have several of the Black and Decker cordless products and thought I'd pick up a cordless leaf blower but the reviews are not good? I bought the B & D weed wacker and really like it. Also have the cordless jig saw - pitiful and the cordless trimmer - haven't used it yet and thought I would piggy back on the B &D batteries i have but the poor reviews have turned me off. Any suggestions for one to basically blow leaves off the driveway and occasionally blow out the work shop. Thanks.
