I have been using the Vision ( Some vendors call it the Stardust) for 2 weeks now while at work. I sit at a desk for 10 hours a day and vape constantly, so I believe I can give a pretty good review about this product. I love it!! Two words sum it up for me: consistent and simple. In the two weeks I have been using it I never have had one dry hit. The flavor is not muted because their is no carto filler. It has worked flawlessly without exception. Its so simple to fill up. Just unscrew the mouthpiece, fill with juice, screw the cap back on. It holds 1.6 ml of juice. I have used the Ego-T and the Ego-C and in my opinion the Vision blows them away. I have seen them available in a couple different ohm ranges ( 2.1-2.4 & 2.4-2.9) I'm using the 2.1-2.4. Pick one up, you wont be disappointed.
