Crash. I just got a Sparkplug and am really unhappy with it. The 801 copper atty vapes terrible IMO in comparison to the 901 on my SD. I wanted to try it because the cart fill area is a cavern in comparison... however, like you described, it is a "dry" vape. More like vaping air to me. I have not tried a 510 and thought about getting an adapter for either that or the 901's I have been using with my SD. I like a real full flavor vape!
