So far the customer service has been great. I did have an issue with a bolt not being included but they sent a new one out to me when I enquired about it. I hope this continues. Hopefully I don't have any major technical issues in the next 2 years, I'm not sure what Vitilan are like in terms of replacing large components like batteries. Which should be free to exchange if any faults happen in the 2 year period. From the website a second battery would cost £400, which to be fair isn't too bad for
