Nice, I've been wanting to get into cold smoking for a while now but I know very little about the details (other than its low temp smoke and you can do it in a cardboard box).
Have you smoked anything yet? Let us know how it turns out. The price point on that item is pretty low, so it wouldn't be a huge risk for me to pick one up.
