I purchased the 21" High-Efficiency Log Grate with Reflective Fireback. First of all: under-promised and over-delivered. When I placed my order I was notified that there was a backorder into late December. It's already here! Nicely handled, TGO! Second of all: this sucker is heavy! Nothing skimpy here; the grate is great and this backplate is NO joke. Performance review: fantastic! Every detail in the product description functions as advertised, from the efficient directing of smoke up the chimney to the increased output of heat into the room. The self-feeding/vertical design is creating a cleaner burn, and I have reduced the pace at which wood is being burned through. The unit is everything I had hoped for when I placed my order. VERY pleased!
