I haven't seen any reviews of this yet so I thought I would share my opinion of it. This is the first clone I've bought, other atomizers I've used are VA cyclone, mark bugs chalice 3, and tsunami 24. So I think it's a pretty great rda for $20, it doesn't dry burn like my cyclone and it doesn't leak often (just from me overdripping). Also the machining seems good, the peek insulator at the bottom isn't the cleanest but it's ok. The flavor isn't as good as it is from a smaller chamber atty, but it makes up for it in the volume of vapor. It's also easy to rip through a lot of <a href="http://www.vapininthecape.com/eliquid_c_7.html”>juice with this clone, which isn't the greatest if you're trying to quit lol. Also I watched the toddsreview of the authentic haku and the measurements are close to the same if not the same.
