Pros : works quick and hot when plugged into outlet with enough current
Cons : hard to wait for three hours to see the finished product, but that's necessary.
Other Thoughts : if the kiln is not getting hot, try another outlet. It turns out the first outlet I tried, though there wasn't anything else plugged in at the time, wasn't strong enough to fully power the kiln. Once moved, it worked as promised. Looking forward to experimenting. For jewelry sized items, 12 minutes was a little too long for contour fuse.
