Check this out..

It looks very similar to a unit a friend's son has that I've "tried" to use.
If the same, it is CHEAPLY made.
It has no vents and the "sliding" doors quit sliding about half way through our first attempt at using it.
It is much more like an ECB than a WSM.
We were only successful because of my ECB experience, our willingness to sit right in front of it and fiddle for 10 hours and the fact we were smoking a butt and they're basically indestructible.
If you don't mind constant babysitting then ok, but
personally I'd never purchase one.
