Lenny,
I bought one earlier in the summer and havent been out with it, though I have filled with kit and wandered about the house on one or two occasions! Other than that, its not been used, has the tags with it and I bought it in Cotswold Camping.
I've hummwed and ah'd about which of my bags to sell and I've put 5 of them in bin bags and up to now I've not doen so with the Kestel, but its going and I'm keeping my golite bag.
