I've been sending my Inspira to the Section 13 SC past few services. Am satisfied with their service and they do allow me to bring my own EO. I was not told about any void of warranty though. Recently however they have service to order the oil that you need so I may do that instead of bringing my own. I use Syntium 3000 which I get from one of the spareparts shop in Sea park near the Shell/Maybank area.
