Hit or Miss?

I purchased this product for myself and my mother. We both live in Southern California. She uses hers every day and loves it. It used mine for 3 months in the last year. When I fired it up this year - no heat. No better than a fan. I've tried it at various settings and it won't put out heat. I was thinking about ordering another one - no. Please be advised by our experience the quality of the product is hit or miss. I struck out after 3 months.
