and what made me send it back was the fact that a few minutes after use it started smelling like melting plastic. It stunned me because there were so many great reviews and I understand why people might initially like it as much as I did, but I'm wondering how many people have actually used them and maybe they have a different model or another version than i got. I liked the nozzles too, even picked up a circular saw and used it enthusiastically, but after just drilling a few holes with this thing it obviously won't last long and a toxic plastic smell was enough for me to put it down pack for return. So I didn't even bother trying the circular saw any further than plugging it in and pulling the trigger a few times, it was one of those throwbacks I figured I wouldn't have to do if the part was just a little would have been done better. . My thoughts that maybe I got a lemon and should try again vanished as I read more reviews similar to my experience. The only reason I went with this is because replacing the batteries on my old Black and Decker battery powered drill was more expensive than the cost of the entire kit including the cost of the circular saw attachment. Great idea but too many corners were cut to make this item so I couldn't cut anything without feeling dizzy from the smoke and possibly starting a fire.
