If you’re not familiar with electronic cigarettes I would advise you to read this post before reading this one. : http://technologyinsanity.com/technology-reviews-guides/dse901-electronic-cigarette-review/ It was a review, but I basically went over electronic cigarettes in general 
The DSE 901
I enjoy this electronic cigarette, it was my first and works very well. However, I did manage to kill one battery right off the bad, which I’m not too happy with, maybe I was just unlucky. One still works though, and I still vape with it.
The DSE 901 is also kind of hard to get a good hit of vapor. You have to suck kind of hard to get the atomizer activated. Not a real big deal, and the best performance is always dripping the e-liquid directly on to the atomizer. The carts were really weak for me. Other than that, I was satisfied with this e-cigarette.
Another thing I did not like about the DSE 901 was the mouth piece. I kept chewing on it for some reason, and it did hurt my teeth to a degree.
The Janty Dura-C
Just got this e-cigarette, and I’m really impressed. Everything I disliked about the dse 901 is gone. You push a button on the battery to activate the atomizer, letting me have more control over the vapor. This is a definite plus, you might not realize it now, but if you use e-cigarettes a lot you know that activating the atomizer can be a pain sometimes. With this, you just click the button and inhale.
The carts that come with the Janty Dura-C are also much better than the DSE 901, so if you’re a cart user, this is a much better option than the DSE 901.
The entire device, looks much more polished than the DSE 901. It has a nice rubberized feel to it, and offers plentiful amounts of vapor. I would go as far to say that the Janty Dura-C exceeds the vapor production in the DSE 901.
The mouth piece is much more comfortable, it is rounded and feels more like a cigarette. It also has that rubberized feel and I do not feel the need to chew on it with my teeth. When I drip on the Dura-C it produces PLENTIFUL amounts of vapor, maybe more than you even need. It’s very sleek.
The battery life isn’t much better or worse than the DSE 901 in my experience.
If you love the LED on the end of electronic cigarettes, then this will be a drawback for you, there is no LED.
Conclusion
If I was purchasing now, I wouldn’t even bother with the DSE 901. The Janty Dura-C is just a better device all around. However, they may be hard to get a hold of, and I would still wait until the new model is tested fully. I will update this post about any failures or anything of that nature within a few weeks. 
YouTube Review
UPDATE - I’ve had the Dura-C for 2 weeks now, and there have been zero failures as of yet. I will update again in 2 weeks.
UPDATE #2 – No failures. I think it’s safe to assume I’m in the clear. I know others have reported issues, but I have had no problems except one battery *appeared* to have died, I tapped it on a hard surface a few times and it has been working fine now for over 2 weeks.
I buy some of my e-cigarette products from here you should check them out.
