This was the second ever Jet tool I bought about two years ago. It had been serving my home shop very well. I have not had any problem with it whats-so-ever. It always starts when I need it. I had couple of times the dust was up to the neck and this thing was still going. It is pretty powerful for its size and that class of dust colloectors as I understand. I made my own 5 micron bag and plan on making a bigger lower bag or add a "window" to it. My shop is 10'X12' and this thing does not take much of room. So it's recommended if you have a small shop and don't run more than one tool at a time.
