Everything I didn't know I needed!  I bought this last month (Jan 2017) and assembly was easy-breezy. I live in Florida, so this more than suffices my fireplace needs. The flames/logs look about as real as an electric fireplace can look. I have used it just about every day.  So far, I really can't think of any negatives about this product.  I am very impressed.  Well worth the price.
