The kiln arrived within the estimated time frame and was extremely well packed. I primarily anneal small items and beads at 950°. I think this kiln is going to be very efficient and cost effective because after 4-6 working hours, holding at 875 ° the outside is barely warm (great insulation) and after shutting off at 700° it take much longer to come to room temperature than my old kiln did. (It is larger so that may account for that.) The controller programmming was a bit difficult to figure out in spite of the 20 page book that came with it (too much info all at once?) but after about an hour of playing around with it I felt quite capable. The display is small but very easy to read with a lot of information visible at a glance. I have only fired a few times to date, but all in all I am extremely pleased. Also, Soul Ceramics was great to deal with, followed up with me on a regular basis after I placed the order and provided amazing response time for inqueries. Very satisfied!
