Query: techno garbage

This thing is such garbage. Rule number one with wiping the surface of the disc is to not go with the grooves in a circular motion. It is recommended to wipe from the inside to the outside. This motorized cleaner does it with the wrong circular motion.It's loud, it tips over easily & the cleaning pad is quite small.Another commenter mentioned that if you need a new cleaning pad you have to re-buy the whole contraption. This is wrong, it's simple to buy a piece of microfiber fabric & replace it DIY. There's a few screws holding it in place.I ordered mine from amazon seller "Computer Geeks" and what arrived is not all black. It's half black, half grey & the spray bottle is half white, half blue. Sooo tacky.I prefer the circular hand crank disc cleaners, they are made (or branded) by many electronic media companies like Philips, Scotch & Memorex. they have a spinning cleaner on a gear that keeps the wipe motion perpendicular to the disc's motion.
