I just received the new red and black unit....The instructions state that the battery door is magnetic but I found that all the doors are secured by 4 small hex head screws each. Also, The instruction state to see " the graph" for atomizer specs, However, no graphs are included...The 510 connection is pressed and not glued but the connection pin is fixed and does not float......Some older atomizers do not touch....Bummer....Last issue, the internal battery last about 8 hours with my Uwell crown set at 50w...To tell you the truth, my Sigelei 150 tc blows this unit away....Sorry Vape cige but this is the truth...... Any body else has any issues with this unit please let my know.
