I can't say anything about the durability as I haven't had it long. However, due to the placement of this and other flame lamps I've tried, they have been exposed to a wide variety of weather conditions including rain, snow, extreme heat and cold. These are the only ones I've had that didn't disappoint in these conditions. So I think their durability is higher in inclement weather compared to others in the price range. If you are looking for a super bright flame lightbulb, I would go further. They're weak, but since I understand I have neighbors who might not like having seizures all night, they're perfect for my application.
