Query: Poor reliability

I found the product does what it is designed to do ie provide heat that is direct and focused to keep one warm. The problem is reliability. I've owned 2 units. Each lasted about 13 months, one month over the warranty. Neither were mistreated in any way. When I contacted Soleus customer service about whether they've had quality control issues, they couldn't have cared less.
