I just received my K02 and love it....I am a model railroader and working on the foam mountains as a base for my scenery.
Without casting aspersions, model railroading is a huge hobby and most model the coal fields of central Appalachia. And the hot tool all of them use is from Woodland Scenics. You probably know of that model they make. However, it is short-lived. I have gone through three in two years...the electronics burn up.
But your product is wonderful. You SHOULD buy an add in Model Railroader and/or Railroad Model Craftsman. I think you have a real winner with your products.

Everyone who owns the hot wire tools should have this case. Everything fit into it and you carry it anywhere and all tools are protected. Wonderful item

This is the best to cut thru foam with precision.

This tool will help keep the wire straight to be able to sculpt into the foam. Very nice

This product is amazing. It really is a strong bond and you use so little of it to make that happen.
