At this point I have over 30 hours run time with this machine. It has been extremely effective at removing burnt Teflon smoke odors from washable fabrics (clothes, sheets, curtains, etc.), difficult/impossible to wash items (purses, sleeping bags, footwear, etc.), and furniture (couch, chairs, beds).
Placing items in an enclosed area (closet) works well. For larger spaces/items I had to use plastic sheeting to 'tent' items or close off doorways.
Pros:
(1) Generates ozone and removes odors
(2) Capable of running multiple back-to-back sessions at 30 min increments without issue, overheat, etc.
Cons:
(1) **warning** If the unit has power it will begin generating ozone as soon as the timer is engaged. Since the timer and the ozone outlet face the same direction I caught a face-full of ozone the first time which made my gums tingle for several hours. Would be much better if the timer was located at the back of the machine next to the on/off switch. Workaround is to set the timer, place the unit, then plug into power supply.
(2) Hygrometer is battery operated (watch battery)
