Paul,
What was the nature of your use? Off-season storage only, or year-round protection? I ask because of the fan life.
One review on Amazon stated that the fan died after 10 total months of use (a few fall/winters), whereas another said he's been using it for 7 years without problem. The manufacturer's website claims 3-5 year life span on the $60 fan. Because I'm currently renting, I intend to use this year-round...
However, this may all be a moot point if I can't fit in the garage; I have 17.5' of room from Door Sensor to a wall-mounted shelving unit. I'll have to inquire about removing & relocating it, in order to make this 18' bubble fit

Glad I measured before clicking Pay!
