I have a Duraflame model and also this NookNova. I will say the flame effects on the Nook are really pretty good, really bright and realistic flame, its much brighter than the Duraflame models...the main downside is the heater, it's really small kinda cheap looking and sounding. Especially compared to the Duraflame brand which has a higher quality heater. But for less cost, I do like the Nook for the realistic flame effects that do make it appealing. I recommend purchasing this model if you are looking for good flame effects.We bought this to get the atmosphere of a fireplace and it is very nice! The heater works well too and has a thermostat and timer for the heat. It does both very well, just a look of a fireplace without heat and with, depending on what you're wanting. We love it and works terrifically.This fireplace works great on our enclosed front porch. Even in the extreme cold, it warms the space and looks realistic.I haven't been able to set it to run continuously without shutting off. When I'm at home, I want it to run until I shut it off, but it turns off automatically no matter what I do. I'm going to unplug it and leave it off the power for a while and then restart it. If it still shuts off automatically, I'll be returning it. My mother has a similar heater and unless she programs it to remotely turn off and on, it stays on, and that's the feature I want. This one gives good heat but I just don't want a heater that I continually need to restart.Bought this for the man cave for the ambiance and a little extra heat in winter. So far satisfied with the look and performance.Very efficient electric fireplace, takes the chill out of the Roomworks perfect looks great
