I can understand if they wanted to develop a heater properly and not just throw it in their knowing it could be a problem. Still would have been better if they included it from the start .If your selling the product…..the product is launched. And, they have been advertising the product in magazine and tv for some months now. They missed an entire cold season by not providing a heater IMO. And, I cannot understand why. Maybe if they had a GOOD reason they were providing I could understand…..but it's just a heater.
