Pros : The biggest advantage of this kit is that it´s sized to fit in a smaller kiln, one to which I have an equivalent. there´s not enough height in it to rig the pot melt with ordinary pots
Cons : I do agree with others that the pots are very expensive
Other Thoughts : My single hole pot broke too, but I used it anyway since the construction with pot stand allowed me to just piece it all together again. Used it several times since, no problems.
With such a small kiln as I have, don´t expect those mega cool mega swirly pot melts. You will get some very pretty and unique art glass though :) .
If using bullseye glass - read the charts concerning which glasses might react to another and you can avoid swamp colored glass if you don´t want it.
