E-Cigarettes? I hate to say this, but those things are crap. A really big waste of money. If a newbie were to try those things first, they may give up on the whole vaping idea, not knowing there are better cigs out there. I wish I had a way to talk everyone out of those things and save the money for better products.
I'm still using Janty Kissbox Classics. I have three and love them. I'm not even thinking about trying the Dura til maybe around Christmas. A few of us here were the firsts to try the Kissbox when they first came out of the shute. There were several problems with them in the beginning. I ended up having to send them back and get replacements. Now, I have beautifully working Kissboxes that I use daily. Yeah, I wish I had waited til all the bugs were worked out. I wouldn't have been so frustrated.
As far as Janty USA, I've never had a problem with him. I just ordered some more cartridges for my kissboxes a couple of days ago and got confirm today that they were shipped.
I remember when we had problems with the kissboxes...and there was lack of communication from Janty. That's because they were busting their asses to get the problems fixed. If the Dura's got bugs, I'm sure that's what's going on right now. Try to be patient. You'll eventually have your product....and it will be working too!
Just my 2 cents worth.
