Does what it needs to
I bought this to replace an older MEGUIARS model which expired after maybe 6 years. This is far better balanced than the older model and does what it needs to. Vibration is less and it is easier to hold. It did pack up once but undoing the brushes and refitting sorted that (and it has been ok for maybe 2-3 years since). It seems overall more efficient than the older one and I am more than happy using it. I would probably go for another make next time but only as it widens my experience as opposed to being unhappy with this one. The old model was a disappointment but this one is far more robust. I use Scholl pads and compound with it and it all seems to do the job perfectly :)
