PA,
Did you post in baso's forum?
You'll get the straight scoup here.
You might be able to post where you and and we can find someone in the area who has one for you to try.
They're 100% safe on a deck. They do not put out direct heat and with 800 degree insulation, the hottest they get is when hot air escapes and the vent get's hot.
As for food it's subjective.
There are some that love it, some that don't.
It's a very moist cooker, and as such will help the normal smokers achieve a very good product. Just read through the forum for comments from actual owners.
The heat control in this things is a set it and forget it, you don't have to concentrate on that.
As for flavor/taste, the biggest difference is because of the humidity, some of the meat can get a steamed appearance, but I always recommend if you don't like that, just open the door, let some humidity out. It works fine, it's just knowing the tendency of the specific smoker.
And as you read, notice that people will say they get oversmoked wood. That can and easily does happy, because it's not using wood for heat, it's using the heating element. So adding or not, more wood, is easy to sort out and get all the wood taste you want.
I'd also pick a forum that is what you want to cook, say ribs, and see what people are posting and saying about it.
Note two things:
1. CS has a money back guarantee, so don't worry, if that's the issue. Over the years here, maybe 10 or so, I can't remember maybe 10 being sent back. It does happen, but that's why the return policy is there.
2. Look at the comments about Customer Service. CS stands behind their customers.
It's REALLY difficult trying to quantify the quality/taste of the product you will get.
Any specific questions you want to ask?
