The improvements are there right from the outset. User control is very much enhanced when compared to single handed buffing tools, especially for a reluctant body-man like me. This machine is well made and it works with the RYOBI ONE+ system batteries of which I have several and I found them to be very good. The orbital action together with the large, ten inch, buffing pad makes a winning combination for expansive areas that don't have too many intricate folds, bends or creases.
