I didn't
buy it for my Provari. I had done research on the Provari for a couple of months prior to buying mine, and based on the few problems that customers had with their Provari's I decided I wouldn't need it. Just knowing that Provape will fix a Provari after warranty for repair costs (already posted on the website, item for item for part replacement) was good enough for me.
However, if you want that extra security of a second year under full warranty, go for it.
