I don't know what kind of problems with the Satellite kiln you have
heard about, but I have a medium size Satellite kiln that I use for
wax burnout when casting. The interior dimensions are 9"X9"X9". I
have had it for over 30 years, use it regularly, not only for
casting, but also for enameling when I don't want to heat up my large
Vicella kiln. I have never had any problems with it. My burnouts have
all been successful.
Mine is the inexpensive manual type --not the expensive programmable
one, so I do have to attend it as I step up the temperature when
doing burnout. If I was considering getting a new one I would
probably prefer the programmable one, but as my current one is
working so well, there is no need for me to change.
