My first real device was an Ody (remember those?) loved it, hated tubes from the get-go so I built an 18650 box for it, it was my go to unit...then I bought my first Reo...a gold mini...honestly after vaping an Ody with 1.8 ohm coils, having to go back to attys with their super tight draws (for me cartos were out of the question...and those 14500 batts

)...the Reo just didn't take, but what did take was the bottom feed thing and if you guys ever seen any of my early YT vids I've been bf'ing drippers for a long time...then I started into Grands, waaay better but you know what? (and I slap myself) it never occurred to me to LP a Grand

but that's ok, because ERA's and the little iGo S's were pretty good...then I saw my first LP'd Grand (OMG! Duh!)...at that time I didn't have a one so I jumped on the classy's, bought yet "another" Grand and ground it down...
Sorry, for the history lesson you didn't want but the bottom line is, of the almost 5 years I've been vaping I don't think I've not owned a Reo product for more than 4-5 months, I've built and bought a lot of mods over the years and currently own over a dozen (now, all bf's)...
would I vape without a Reo? of course
would I still be vaping had I never owned a Reo, that's questionable...
would I now be without a Reo in the line-up, definitively no...
I can build a mod that out performs a Reo but that's not the point...rarely have I come across a product that the creator literally deserves to be recognized...call it what you want, but so much of my vaping enjoyment is based on my experience of (and shamelessly copied) from Rob's products...my dad always told me... "pay the man for services rendered"
