Pros : Easy to program, easy to use. I've had my kiln since December 2006 with no problems other than replacing the relay switch a couple of years ago, and the lid coil today. This kiln has had moderate to heavy use and is very reliable. Would I buy the same kiln again? Absolutely.
Cons : None that I can think of.
Other Thoughts : You can watch a video on how to change the coil, but to tell you the truth, he makes it look easy. Because my coils are so old, they are really stiff, and didn't want to come out of the track. It was much easier to get the new coil in than to take the old coil out. About 2 hours to remove the old coil, and only 45 minutes or so to put the new one in.
