I have a Klim vest with in a motion technology for three years. There vest has never worked properly and the module has given lots of problems which means I never have the vest when I need it. Klim is a purchase and subscription system which doesn't suit a lot of people as you are on the hook for money all the time you also pay an additional subscription when you use race mode. Now to get to my new vest. I dealt with a fellow human being not someone by email. They transaction was seamless and very professionally. William also assured me that I can contact him personally if I have any problems. This is a one off sale with no subscriptions, no updates on technology so I now feel this is the vest I should have bought in the first place. You live and learne.
