I have 4 broken bottles on my one month old 2.0. I have had an XL since January and have broken no bottle. I contacted Vapage about a week ago which was very time consuming and a hassle and when they finally replied to me they still didn't address my problem, they only told me that the bottle for the 2.0 was only supposed to last several weeks, which they fail to let you know that when you purchase it and I see that as they really don't care about customer service, just making money. After 4 emails later they finally tell me to print an RMA form and send in my unit that I didnt explain earlier in this post that the press fit innards of the chassis won't stay in the chassis. I found this to be a big hassle on my end as I have spent hundreds of dollars at Vapage and referred many people to them. I wasn't looking for a handout just wanted to get my 2.0 fixed and it took 4 emails to get the info from them. I'm sure you can tell that I'm not too happy with Vapage
