Thanks again to the Voltaic team I will be running our whole fleet through them for sure!!
Voltaic (in conjunction with Elite Tune) completed an outstanding mine spec upgrade of my dual-cab LandCruiser. High quality work, very tidy job all round and will be using them again. Would recommend.
Dropped in my 100 this morning with aircon issues and was fixed by mid arvo. Very happy with the communication via messages and not only phone calls made it so much easier all round. Great consumer service. Give these guys a crack they know how this stuff goes. Will return, one happy customer 🤙
