Effective!

The only con I have about this is the assembly. Didn't go to smooth...had to use different screws because the ones included were weak. For the price, it should've came preassembled.
But aside from all that, this thing is great. Very dry & up front vocals.
If you need a booth but don't have the room, get this!
Looks great too.

Should have arrived constructed!

I think $399 is overpriced considering you have to construct this thing completely. They make you do everything apart from saw wood!! I take it you are paying for the panels which must be made from some kind of mystical substance bathed in unicorn's blood or something developed by NASA as I can't see how some loose planks of MDF come to this cost.
A handyman could buy the loose panels and make something similar at a fraction of the price.
Having said that, the thing works great for what it does and I would have given more stars were it not for the amount of construction you have to do - that side of it gets 0 stars from me.
