I couldn't be more pleased with this unit.  It arrived securely packaged with blocks of Styrofoam in strategic locations and layers of plastic to protect it from damage.  The unit is located in my bedroom; it replaces an older electric unit that suddenly failed and I was sorry to lose as I could not locate a replacement for the failed flame unit.  But the many features on this unit, the variable flame effect, the welcome addition of the timer, the attractive appearance of the mantel, and the effective infrared heater have more than made up for the loss.  I like the wheels, as those will make it easy to move the unit for cleaning.  The flame unit itself is very well executed; the glowing logs and the glowing embers provide just the right ambiance.  While it would never trick the casual observer into thinking it was a real fireplace, it doesn't absolutely scream "fake," either.  For my purposes, I consider it an excellent purchase and can wholeheartedly recommend it.
