Got this a few months ago as a beginner to rebuildables. It honestly got me hooked. May seem like a hastle to build coils but the money you save is insane. the flavor is incredible even on my cheap mod. But the low capacity though mean. You have to constantly unscrew the tip to refill. Which leads to its fatal flaw. The plastic tip. The part that screws in to the main tank just snapped on mine rendering it just about useless. So this is a good piece to get your toes wet in the world of rebuildables. But be cautious of that plastic tip.
