I recently started trying VV box mods. The first one I purchased here on ECF classifieds. I do not want to mention the vendor but it is a low priced mod at $34.99 the first one I had for about a month and a half. And the connector spun loose from the epoxy. Broke the wire. So I stepped up and bought another one this time I bought a new one directly from the vendor. I bought it on 9/10/11 and tonight on 9/27/11 I was un-screwing the cartomizer and the connector came out with it. The mod has a 30 day warranty (I think) so hopefully they will replace it. But it seems like it is a major design flaw or on going problem with them. I am wondering if anyone else has ever bought one of these box mods and had the same or similar problem I am having? I love the TH and vapor production I get from the mod, but $35 for 17 days of use seems to be a little excessive. I would love to hear from anyone else that owns or have owned one of these mods.
