ok fine, but the wattage still changes on any vv device though, its being varied on the provari too its just not determined by it, when im happy with a pv, reliablity and life span of the device is my main factor in choosing a pv, vv is great but a 100% mechanical mod will be more reliable when choosing a secondary device.....good old murpheys law proved itself to me acouple months ago when my main device and my backup kicked the bucket within a few days and i found myself using an old box mod for a week while waiting for my provari to come in the mail. all i had left was this plastic box mod and i found out that it was having issues too, if i didnt turn it off the main switch everytime i used it it would remain on...the atty got so hot it melted the unit into goey plastic it eventually cooled down and hardened again but it happened twice i was about to be left with no device if i wasnt careful about flipping the swich off when i was done vaping it...and btw for future reference, as far as the whole evolv thing and my issue it is neither here nor there, if my experience happened to you how would you feel about it as a review...theres a lot of good mods out there just because two have rave reviews doesnt mean an individual would find it appealing, now a days people may not be looking to spend over 150 bucks on a unit, ive seen ads lately for non-ego starter kits (sparkplug v3 for example) for 25 bucks, etc.
