Hey hey. I recently just purchased a second Admiral clone off Fasttech in brass because my first clone was starting to get all beat up..unfortunately when I fired it up, right off the bat I noticed I wasn’t getting such a hard hit as my older one leaving me quite disappointed. I used the same RDA on both so I know it was the tube. The first one I purchased was off eBay and even though it was a little more expensive it was definitely worth it! I’m assuming it’s the material not being true “brass” and as conductive maybe? The eBay one I first purchased is brass as well. I also noticed this Fasttech one after a few days of use it hasn’t even started to slightly patina it seems. My eBay one when I would give it a light sand it starts getting patina after like 1 day. Bahhhh...what do you guys think ?
