so yesterday my hh357 decided it was going to die after only 3 weeks of use ,performance was starting to diminish so i decided it was time for a cleaning , which was the second cleaning this atomizer has seen . after the aclohol soak I blew it out and primed it , let it sit for a few then screwed on my megalodon and low and behold it was dead as door nail . well up until that point the hh357 was great . so i switched back to my aero atty which is about 2 weeks older than the hh357 and its still working but gave me fits all day so that one is due for a cleaning as well. fast forward to today i had the mailman bring me a new bridgeless 306 from empire to try out in my new dca. this is my first 306 and i have to say its every bit as good as the hh357 and its less than a third of the price . hopefully the lifespan is good on theese if they are then im hooked for both value and performance .oh and the dca is a wonderful device as well
