Black & Decker Polisher

I bought a Black & Decker Polisher from Tesco yesterday.
With the polisher I can polish more cars in a day.... :P
It was a tired job to polish 3 cars in a row at home....
I used it just now and I felt it was quite good, my polishing job was faster than before.
The bad things is the polishing sponge will damage after 3 to 4 cars according to manual.
Replacement kit will cost 20 bucks; but I asked my mom to make some replacement kit for me :P
