I didn't get Celotex, see above. The Recticel I received is reasonably easy to handle and cut. I had chosen Celotex on the basis of recommendation, I don't know how much easier/better/more difficult/more pleasant Recticel is to use compared with Celotex.
22-Aug-2014 Product:
Generally good service.

I think the RMA process is a bit daft. Someone on the end of the phone for returns rather than the email system would be better I think.
