This fits beautifully on our patio.  I know the height is a safety feature, but it does mean that if there is much wind at all you don't get much heat if you're sitting under it.  However, this isn't really a 'problem' so much as a 'know what you're getting when you buy this kind of heater' comment.  It's already letting us use our patio when we otherwise might be inside, so we're thrilled!
