I got 11 days on my first IKV Fusion LR and probably could have gotten more. The ohms went upto 2.0ohm from 1.7-1.8 and i did not want to risk it since it was time to fill the tank again....not bad imo for that juice. Its 70PG/30VG banana nut bread which is sweet but semi clear.
Ive got one still going strong (need to look up the date) i filled a day or two after the first. Its also 70PG/30VG, kinda clear but not quite as sweet. Its a mix of a local B&M Mango juice 12mg and some very clear LIQUA Strawberry 18mg (trying to cut down on the nic). This one is still working great and its probably been 3 weeks, I will double check the date after this post.
EDIT
Yep, i filled this one on 11-06-2013 and im sure its been through close to 30ml or a little more.
I do have one complaint on the 3rd one.
It made my Blueberry Waffle 40PG/60VG nearly overpoweringly flavorful.

It did the same thing to a 70PG/30VG blueberry cream. The flavor is so intense im going to need to thin it down or make a special order next time on my juice. The cream part is just too much now so i mixed it with some straight blueberry juice but the cream part is still overpowering.
Thank God my Banana Nut Bread is perfectly flavored. I would hate for it to be too intense. The fourth one is rocking with it right now at 7watts. IMO the Fusion LRs are fantastic at 7watts on my MVP v2 with the juices i get. Any higher i can really tell a difference. Not a burnt flavor, its just not as good.
