Never been big into tanks. Always had one for convenience but preferred rda's . My favorite has been the Crown1 and still is. I got a Freemax Mesh recently and I am really liking it. It hits hard, harder than my Dead Rabbit with a challenge cap. It is really well made down to the coils.The airflow is huge, but it does tend to close while being carried in my pocket. I love the form factor. I like compact devices and it is very short. I have the black one but I am wishing I got rainbow. In that color scheme it is one of the coolest looking tanks I have seen. There are a few drawbacks. It is small therefore has a small capacity. (3ml) which Ihave had smaller tanks but this thing guzzles juice. I DIY so for me it's not a big deal but if you are using premium e liquid be prepared to spend some $ .It is loud. The airflow is louder than any competition rda I have ever had. Also, maybe because I am using so much juice, but I seem to be much more dehydrated when I am using it for the day. So be sure to drink plenty of water.. .
