I've got one first IQUE 110 that they made and I use it on my Stumps Clone. I don't use it to get it up to temp, but once I am with in 15 or 20 degrees I shut the fire box door let it take over from there. It does a realy good job of a maintaining the temp. I have ran it for 2 days straight with no problems. Some things I don't like about it is it don't have an adjustable fan like the new models. Hose isn't long enough, temp probes don't last long. With all that said I would buy another one. I made a weather proof box to place it in when it's windy or raining. Will post a pic later.
