The Eleaf iWu became my favorite on-the-go pod device very quickly because of its terrific flavor reproduction and long battery life. I use it with regular e-liquid and it delivers superb flavor. The iWu will handle 70vg juice nicely, but the best flavor is from 60vg or lower. It's an awesome pocketable pod device because the cover slides up to protect the mouthpiece; plus the sliding cover keeps constant pressure on the pod so it can't be accidentally dislodged in my pocket or backpack.
The iWu really shines when it comes to battery life, the 700mAh battery lasts throughout the day, never needing charging till bedtime!! I've been using the iWu for almost a year and it has functioned flawlessly and, even tho carried in my pocket/backpack, it still looks brand-new - amazing finish & durability!!

I love the sleek look of this product. It does not leak AT ALL. It is easy to refill. The only issue I seem to be having is that the cartridge tends to not sit fully connected so I have to keep pressing down on it to make it work. If this could be improved and I could find the replacement cartridges locally, I would never use anything else.
