I own three model 733 circulators that are four or five years old. I own a century-old farmhouse without air conditioning, and moving air in the summer is necessary for living comfort. The multi-position base and multiple fan speeds allow for total versatility and maximum comfort. The sound from the blades and air on the highest speed does make hearing the TV a bit difficult. I am a sound sleeper, so the sound does not bother me in the bedroom. My only complaint is that with years of use, the little rubber feet on the fan base have fallen off. This was repaired by purchasing the little rubber self stick bumpers from the local hardware store. This model costs more than other fans, but the quality of this fan means that I won't be sending it to the landfill in two years. This circulator does what it is made to do, with dependability - and it is made in the USA! 1,000% satisfaction!
