Well to start with I really wonderd if this tool was going to save me time removing 75 years of paint on my mother in laws house. I orderd it and went right to work with it,about 3 days later I had a large old ranch house down to bare wood and ready for priming. I found that the house had been at least 7 different colors in it 75 years. When using the the stripper  I also used a full face shield and a resperator along with a long sleeve shirt and I put a bib on so that i wouldnt have paint going down my shirt. I also found that the metal disc. would sometimes clog with paint, so I would take a propane torch and burn the paint of the disc and then continue on. I did end up wearing one disc plum out and so I bought a new disc to finish up with. The stripper is a little heavy and your arms are going to get tired but my wife used it after I suspended it with 4 long bungee cords above the location she was working. The bungee cords helped suspend the tool and take the weight off the user. Anyway, the tool is very well made and plenty powerful and it beats trying to use an acid stripper. I will probably use it next to strip the paint off the cabinets in the old house and then make new doors. I can see where a home owner buying an older house could really save alot of money buying this new tool. I build high end custom furniture so i really nit pick my tools not only in there upkeep but in their performance as well and i don't keep any tool that doesnt perform. This new Porter Cable does perform very well and I feel that if your need is for a tool like this the Porter Cable stripper is the only way to go. No more messy & expensive chemical strippers.
