Thats similar abe. The one you posted is just a sander, and in vibrates the pad. The difference is the one i posted is a orbital sander. It vibrates while moving in circles. Like a 2 for 1 kind of deal. Either will work. You'll do just fine with yours. Just remember not to stay in one spot to long with any power sander / grinder. And if you can try not to push to hard. Let the tool do a lot of the work for you. It will take you some time, but good luck.
