This was a much needed product for me. My juices are typically pretty thick, and this bad boy lets me really create a hole punched carto that truly works for me. I've used it to punch a half dozen cartos so far, and it's worked perfectly. I can't rate the lifespan because I've only had it for a month or so, but I can't imagine it not working for a long time. I just got a new Provari, and didn't think vaping could get better, until I got this guy. Great deal on such a useful device. Comes with a keyring attachment, so I'll probably pick up an extra one on my next order to keep on my keyring. Thanks for the great deal!
