Yes. I am a mekkie from way back. I started before good-- meaning more powerful than 15 watt-- regulated devices were available and it was the only way to get the vape I wanted. I now use regulated mods more often than not, but I still love and use my mechs; indeed, I am still in the market for top-drawer tubes and pick one up when opportunity and cash flow permit. I particularly like the ones capable of true-hybrid usage. I like the simplicity-- the engineer in me thinks they are elegant-- and the challenge of building the atty to get the vape you require within the limits of available battery voltage. Aaahhh... how I miss MMV being in the tube business.
