Anyone else have a Hanamodz dna 30 and have problems with it? Gonna send it in tomorrow to get checked and have the spring loaded 510 installed so I double checked today and it is still giving me dry hits and a pretty low wattage on my Subtank nano. I love the mod but am always have trouble with it especially compared to my sigelei 150 that is a absolute dream to vape on. Anyway just curious. Thanks
