We purchased 2 of these and connected the extraction hose in series, to do some simple dust-extraction prototype testing and everything worked as intended! I was really surprised with the quality of the tool, for the money! Highly recommend. The only downside i have to this dustcollecter, is that it only comes partially assembled and it took me about 1 hour to finish assembly. Very easy assembly, but would be nice if I didn't have to do it myself. I don't have any pictures, but it looks exactly the same as in the picture here on the website.
