I would definitely do the paypal dispute.
The problem is also that they should not sell Internationally at there current prices if there not willing to take a loss. The policy to pay for age verification and return shipping on a DOA mod is ridiculous as well.
I have only had 2 problems, the first was a Hohm Slice when it first came out, the Red had damage and they swapped it out no charge. The other was another Slice with a button that got stuck every so often, they sent me a couple of new buttons with a link to a video on how to swap it out. The first time I had to push though and was pissed, I paid full price at the time. They did make it better but there bedside manner when there is a problem can be hit or miss.
If there still available at ecig.com then I would definitely get it there over vaporcube.
Unfortunately I think we are in for dark times with a lot of US companies in the vape biz. I have noticed a lot of online retailers I use to do a lot of biz with have really cut down on there inventory and a few have outright closed. If there not making much money anymore then CS is going to take a hit with any company. Stupid FDA is just killing the US vape market while strengthening the Chinese, sad times indeed
I just checked ecig.com, didn't see any G2's there, in fact there is not the selection there once was there.
