This is some feedback from a NSWR member who used him.
'I just wanted to say a big Thank you to VMAX (Jason) for awesome friendly service. He drove all the way out to North Ryde, I didnt even have to leave work or get my hands dirty. He supplied and fitted a new battery on the same day. Awesome service
Thanks and I would recommend him to any other NSWRiders member if you need a battery delivered'
