I was on the fence about getting this; I already have a name brand SDS max drill so I thought this wouldn't be much better... I was pleasantly surprised to find out I was wrong; this thing is a beast, it tore through a 4-6\" thick concrete path with ease, I took my time and still did around 32 sq ft in about 3 hours. I'm glad I read the reviews before hand so I knew it needed the oil adding because in the manual that bit isn't explained until the end. Mine did come with a tube of oil so I just needed to add it. That said, the manual is pretty decent and easy to follow. As others have said, the case isn't really going to stand up to being dragged around but it's nice for storage. In my area, this worked out cheaper than renting one for a few days, so I was skeptical but I'm really impressed with it.
