"want to be a little more thorough in my description.
Dare I ask why though? It's the words in the title which potential bidders will be searching on, and anyone even remotely interested in what you are selling will already know quite a lot about the product. I wouldn't worry if I were you.
You have some real one-offs in your possession, of this there is no doubt. I do think however that some of the prices you have listed the goods for have yet to reflect what people are willing to pay. The one which caught my attention of all was the Polti water vac. I had one of these in my shop once, purchased as an end of line bargain from a supplier. I literally couldn't give the thing away. It went to a charity shop in the end.
