Not too small or too big (fits nicely in my bra).
Draws without the need to press the button (oddly satisfying).
Holds a decent amount of e-liquid (I use mine regularly and only fill up once or twice a day).
Battery charges quickly.
The cover cap is a nice idea but it doesn't stay on tight and can be easily popped off and lost.
All the sides are rounded, including the bottom, so it cannot be set down on a surface in an upright position, you can only lay it on its side. This means that you can't set it down when re-filling the tank, otherwise the juice will spill out.
With regular use the battery only lasts about 12 hours.
When filling the tank you have to pull the entire coil out which is gooey with e-juice.
The instructions don't tell you that there's a small, flat, screwdriver-like piece of metal under the mouthpiece that's intended for unscrewing and tightening the atomizer. I had to figure this out for myself. Reviewed by: (Verified Buyer) Chanel from Arizona. on 10/10/2017
