First you need to set every single nail below the line where it will chew up the screens on this thing, they are pricey and you don't want to do that
This thing is heavy, you'll need two people to lift it up onto the deck or off the truck
This thing is slow
...but it is effective
You'll still need some little sanders for corners and stairs
Still, IMO, I'd rather deal with all that then try and use a chemical stripper that would leave me with 5-7 gallons of toxic sludge to dispose of, and (more than likely) still needing to do sanding after stripping as it really doesn't work that great...
