I purchased this with high hopes and a little reservation due to its size. it arrives fully assembled and ready to use . we were pleasantly surprised at how well it works. I got the 2 blade 260 CFM version . it is super quiet, efficient and delivers the air flow ( heat distrubution) very well. we are very satisfied with it and highly recommend it . I now consider it a must have for wood stove users. it is great super quiet when operating extremely efficient. and well worth having. it beats the tar out of the competition sold locally. better price, higher CFM and silent operating.we love it and are considering another . get one and you will love it too.
