I got back from a week away to find my neighbour had the bladder a day or two after I paid.
There was an issue with the bite valve being damaged and I let Kit know this.
Before I had time to negotiate a bit of a refund to get a new valve all the money was back in my Paypal.
It is a treat to deal with someone so honourable and up front. I will have no hesitation in trusting Kit with money or good in advance and would like to say a public thank-you.
