Excellent - usually just the mention of the Act brings on 2 responses, a slight widening of the eyes and a faint air of "oh bugger, another one who know's about it", or a blustering waffle about how that doesn't apply to them/these goods/you, because you're supposed to send it direct to the manufacturer for a better service........
Incidentally, if a retailer ever says "leave it with us, we do all that for you" - photograph it from all angles in detail, especially the problem if possible, and keep all your original documentation, give them copies. And get a signed reciept from them with a brief accurate description of its condition that you agree on.
