They certainly provide their customers the best and fastest service. The couple times I have had to send any of my provaris in for upgrades or to remove broken off cartos, they have always serviced it the same day they receive it and have it shipped back the very next day. Each time I have mailed it and had it back in my hand in 6 days. Though even 6 days without my provari was rough-Now, I have 2 as backups so that I will never have to be without one!
