Pros : This was my very first kiln. It didn't take me long to out grow it, but it gave me a real taste of glass fusing.
Even though I'm moving up to the Delphi 15x6 kiln, I will likely still use this kiln for compatibility testing.
The glass that comes with the kiln is great for starting up too! I would order more shelf paper though - you will run out quickly!
Cons : It's very, very small. You can't make more than a pendant at a time. Earrings are a little better, but the kiln doesn't always heat evenly. Also, if you have an explosion (which is inevitable) glass will eat away at the kiln floor, making it difficult to fuse on.
Other Thoughts : In order to use this kiln properly, you need a microwave that heats evenly. You also need to be able to experiment. Glass will shatter and break a lot if you don't learn how to use your microwave's power settings! I cook everything for twice as long as is specified in the guide at half power.
