What have your experiences with it been like? Obviously you can create some very lovely things with it!
It's so versatile. A bit odd to get use to. Takes some practise but so much that can be done with it! The small drawback is you don't have 100% control like you do with clay that you can sculpt and reform but a lot of pluses including the weight and no drying time. If what you're doing doesn't come out the way you wanted - you can remove the plastic, no problem. But if you had too much contact between the pen and the pony, there will be melted areas.
