Talk about Big Bertha!  This one is huge and it’s what most people notice upon entering our home. We had to get an extension arm to accommodate for our 21 foot ceiling so had to get that directly from manufacturer and luckily my husband is a genius when it comes to refitting cause it needed it (slope was iffy!) But all in all it’s good. However,  after constant use for 2 months the thing started squeaking horribly. We turned it off, reversed it and left it that way for a day or 2 and the squeaking started up again. Hubby and bro-in-law dismantled, oiled and repaired it. It works but we haven’t had to use it as much so no telling what sounds will come from it when summer rolls around again. Love the look. Just wish all had gone more smoothly. It certainly does move the air.
