I liked that it is a 5 in 1 grinder and cordless. Having said that, I have found that batteries have a very short lifespan! I wasn't able to grind the pad on a battery. It was also a bit difficult to change the sanding pads. Had to look online to see the trick to removing the plates. You have to turn until the resistance disappears. This isn't a heavy-duty grinder when there's a lot to do! PS I'm an old lady too
