Had a Q100 for about 8 years. Used it frequently and found it quite useful. Unfortunately I did not clean out the bottom or the grease tray for awhile. On day I lit it, walked inside to get the food, and went out to see it on fire!!! Yes, it was a blaze! The debris below the grate caught on fire and fell into the grease tray below. I had to use a fire extinguisher. I may get another if the price is right.
