They sold me a battery for a vape two times now that did not work it would work and it would only hit for like three or four times and then it would start blinking like there's no charge.Even though I just fully charged it to three or four hits ago. And when I took it back to the owner literally 1 hour after I had purchased the vape battery he said they can't do anything that you should have tested it before you left. Which I did but I like how I had stated that after 4 or 5 hits it would stop working. He refused to give me an exchange for another one or even a credit towards buying a more expensive one. This is the second time that this has happened to me at this smoke shop
