Just tried it in two rooms. Easy to use. The Long term effect of it is too soon say anything about.

It was a good device and met expectations.

It works, Works.

Works excellently. Eliminates smoke odor in a 60 sqm house. After 2 x 120 minutes, it's almost completely gone. Very cost-effective. If the machine works, it has already paid for itself after 3 or 4 uses, simply excellent. There are other products on the market but they are 10 times more expensive. Remember to ventilate, hold your breath when entering to open windows and doors. I don't know how toxic ozone can be. You can immediately tell if there seems to be ozone in the air. Very satisfied with the result.

Incredibly effective device, removes odors really well. A couple of times it got rid of the smell and smoke of tobacco from a car that had been smoked in for years.

Works find fore me
