"Unfortunately the brand new fans (right out of the box) did not work properly. Kosta, the owner, then explained it was because the fans were only capable of operating at one speed, low. This was not the case as the fans had multiple speeds as we later found out when paying yet again, to have the fans properly installed. (Now they world on all five speeds.) Kosta did not do the work properly. In addition, the outside timer was also improperly installed rendering it useless. Worse, even though he didn't know how to set the timer he proceeded to install it anyway with a non-trivial charge. The only properly installed work was 2 electrical outlets. The cost for all the mistake and poorly done work was exorbitant -- and that was before the additional cost to hire someone to do the work correctly. Consumer beware."
