Bought this two days ago. Easy to set up, easy to move, and even brought at home in a sedan. One issue: cheap cheap lousy fans!!! They amplify their amplitude, and give that whiiiiiiiiiiiiiin whin whin whin whiiiiiiiiiiiiiiiiiin whin whin whin associated with a cheap fan. it is a pitch and aplification issue, as both fans combine their sounds to produce the effect on a 15 foot radius. Yes, read online reviews with people replacing them with 80mm 10$ quit PC fans, but why should we have to strip wires and do that??? Now, if you store it somewhere such as a cellar, then it is a 4-5 star unit.
