I have owned two of these over the years.I bought one (foolishly)and someone tried to get rid of theirs by giving it to me. Instead of going into a long story I will just tell you that it is inconvenient,smells horrible,the noise of the motor scares the cats, and it is a defective waste of money.I ended setting mine out by the dumpster just to get rid of it. Oh, and the tent you can purchase seperate is very poor quality, a pain to remove anything to change out, and not worth the money.An expensive piece of garbage.Don't believe the hype.
