I first got this tank during an awful thunderstorm here in maryland and I had broken my glass tank so I had no ability to vape. Of course I was no longer smoking and did not want to start again (my husband had cigarettes). I had a fractured pelvis at the time but my husband could have gone to get what I needed. Unbelievably the owner of Vape Dojo actually offered to deliver the disposable tank for me and drive during this horrific thundstorm. I've only used them since. I love them and was amazed he actually took the time during awful weather to deliver them to me. I have never received such great customer service and will ONLY use vape dojo for my vaping needs. This was almost a year ago and is still greatly appreciated.
