I am using a DSE901 and I keep killing atomizers... My first atty lasted about 2 to 3 weeks but since then I haven't had one last longer than 5 or 6 days. I clean them out in the evenings by setting it on a wad of rolled up paper towel to suck the old juice out. I used to blow them out but stopped after that killed one. I had another one overheat tonight and die so I'm watching my use and stopping after the atty gets warm but that happens after about 5 hits. Really starting to get frustrated with the whole deal. I've got another atty on order from a different store to rule out that I'm getting bad attys. Just hoping it gets here before my last atty goes because I really don't want to go back to smoking analogs. If anyone has some helpful advice I'd love to hear it. Thanks!
