Also. After spending over 500 dollars on vapeing mods (vaporizers) myself, i now own a reo. This device is so good i gave away my blus, ego's, vamo, and my tube mechanical mod along with all my clearomizers, tanks, ect for FREE to my friends.
There is a very large group here on ecf that use REOS and love them to death. This group is very friendly and if you have ANY questions about buying one, what you need to run one, and even how to wrap your own coils: they are there with an answer and endless advise within a few hours of your post. Sometimes within a few min . PLUS the owner-inventor of the REO is active in the reo forums and is supportive and backs his product and provides technical support. Do yourself a favor and consider it. Its worth the initial investment
