The Gemini is a WELL performing, exciting new dual coil clearo by Oakley Technology. They have taken pride in it as evidenced with their own embossed branding on the clearomizer. We put it through some tests. We were very pleased with its performance.

The Gemini has a seriously secure connection and we experienced no leakage whatsoever in the two days we were putting it through its paces. A healthy sized o-ring is at the base and you first must push your tube over it before screwing it in to the base. Its a very secure seal.

The Gemini has a 4 wick lead dual coil replaceable coil head. The coil head assembly has a long air stem built into it and it screws in near the base. This should provide a tighter connection when removing the mouthpiece to fill the Gemini. But always re-twist the coil-head to make sure it didn't come loose after a fill.

• The coil heads we tested were right around 2.4ohm but the box stated 1.8-2.6. We don't know if that means each unit can be anywhere in that range or if it means they offer those various ohm resistances since nothing was marked. We'll assume they are all around 2.4ohm
• The Gemini has a detachable matching color transparent 510 mouthpiece. You can use your own drip tip or mouthpiece
• ~2.0ml capacity
• 510 connection with eGo skirt.
