Fast delivery, had an initial issue with one of the connections, but 1 phone call and a technical email later all resolved., I have tried racechip previously but I am more impressed with this company.
I am very satisfied with the order process, customer support and i will recommend yo others. Many thanks
When I ordered, there was no stock for the particular car I owned. I waited one week for the stock but had to write in to check what was the status. However, I must say the response was good.
although i ordered product it is yet to be received !! tracking estimates stated it should of arrived by now, prior to order tried calling the local Australian agent no answer or return call
My dad wanted it so I ordered from Japan. My dad told me that it works perfect and highly recommended. We live in Japan and have Range Rover Velar. Dad said it takes about only 3 mins.
I would recomend to have whats app, sometimes I need to talk online and its easir than emails
