There are a LOT of discussion in the FE forum about smoke flavor.
The challenge is to match what you think is smokey with the capabilities of the unit. Everyone is different so we have to help you get the level of taste you're wanting.
First, learn that the smoker burns more efficiently and as such you'll have a cleaner smoke. In the past, you may have gotten used to a heavier smoke so that's the profile you'll have to work to get.
Keep in mind, CS has a money back guarantee, if you REALLY don't like it, contact CS. They want you 100% happy.
But there are a # of threads here, maybe some forum members will point some out that will help you understand how to increase the smoke flavor.
1 is duration (time spent in the smoke zone -- the meat that is)
2 is wood (fruit woods will always be lighter in smoke flavor)
More to come, just wanted to drop a note to let you know we're here to help.
