Software updates and minor cosmetic changes (the newer satin finishes) aside, I can't argue with your statement.Why fix something that's not broken? Provari reigns, and will for more years to come.
The Silver Bullet is a bare bones mechanical mod that is manufactured nearly as well as the Provari and hasn't been updated much since it was introduced some 3 years ago. Still an extremely popular mod that Altsmoke has trouble keeping up with the demand. I could see the Provari being the same. There will always be a large market for a well built, durable mod that is backed up with excellent customer service.
