I suppose the appeal of Dragons Den is that you don't have boffins using professional pitchers to put forward their inventions. Much more fun watching the squirming of the inept. The backers obviously see a good idea, and potentially excellent returns of their investment, even though the poor chap with his egg cooker was left with egg uncooked, he was such a nice chap, and I for one, wish him every success. I like watching the arrogant ones having to go off with their tails between their legs !!!
