Fantastic fan or maxxair ?

Thanks everyone for suggestions and comments , especially those with real life experience . I decided on the maxxfan 6500k manual 10 speed reversible with smoke over . It arrive today from camping world , good sale , $239 free shipping . It will be a week or two for installation depending on weather or shop space . Initial inspection looks to be well made . Don’t think the plastic frame will last 50 years like the aluminum one I’ll be taking out , but then neither will I, lol . The cover does come with lifetime warranty to original purchaser , 2 years on the rest .
