This is a negative review of Vaping Zone. I am a little sad to post this considering that I have used them before and tended to like their more unique products. I ordered a couple of batteries. VZ Leo Passthrough USB Battery 1000mAh One was broken - would only work intermittently and the other died about a week later. I sent a couple of emails about the internment one. They told me they would get back to me. They never got back to me. When the other one died, I returned both. They sent me back two batteries. One that was DOA and they included a very terse note that stated: A) these two had no warranty what-so-ever. And B) Both of the batteries dying were my fault because there was "excessive juice on the contact points." I was incredulous and wanted my issue solved. See: 1) I paid for something and it should work. 2) Being Leo's they are supposed to have a sealed battery to prevent this type of failure. This was an issue with the Leo I's and using the Tanks. It was solved with Leo PT II. (Turns out these aren't actually official Boge products but a proprietary product from VZ calling itself Leo). 3) I was using attys/carts that I had bought from Vaping Zone. These are products that actually go with/are advertised for this battery model. There are no instructions that come with the batteries. There were no posted restrictions. I was using them as I have used my other Leo batteries, entirely without issue. 4) Even if this were true, that is was user error, it doesn't account for the fact that I had gotten two different batteries that didn't work right to begin with. Their website clearly states at various places "14 day replacement on defective parts or DOA. No Refunds. Physical damage is not covered by the return policy." Which means that, even if they were correct, in saying that excessive juice damaged one of them, they should at least extend the warranty to the DOA and the one that never worked correctly in the first place. 5) I actually emailed them about getting instructions, regarding the battery that only worked intermittently and they never got back to me on that. SO I called them. The first person I spoke to was fairly nice and told me that I could return them. I was still upset about the warranty issue. The second person I spoke to, who was very rude, said that he personally tested both batteries. That I would be getting no refund. He stated that I should not return the batteries as he would not replace them. He then hung up on me. When I called back, the woman I spoke to said that the second guy, who was named "Louie", was actually the owner and that all his decisions were final. She apologized to me for the inconvenience. I was saddened by this. As I had bought from them previously and had really been impressed with some of their products. It just seems to me like they got a bad batch of batteries. These things happen. The problem is that owner tried to shove this off on me. It turns out I am not the first person to experience this type of abominable customer service with this company. See ripoff report here: Ripoff Report | Vapingzone.com | Complaint Review: 785600 Further, it's a good thing, for me, that I have a record of all communication and correspondence. I am sure my CC company will have no trouble refunding my money after I send them the phone call where the owner hangs up on me and refuses to honer his own warranty, which, I will again point out, is prominently displayed many places on the site. I would avoid dealing with this company at all costs. If something goes wrong, you have to put up with really bad customer service and you might not even get your issue fixed. This company believes that blaming the customer is a way to solve issues with defective products. AVOID.
