I first used this tool to remove a set of thin tiles on a concrete floor. I used a Bauer 11.5 Jackhammer from Harbor Freight. This worked very well as the tiles fitted easily. The skinny set was a different story. It took a lot of effort to knock it off and I still had to rent a concrete mixer to remove the remains. I'd say using the tool was an important part of the process, but at least in my case, it didn't do all the work like some YouTube videos would have you think.
