Very happy with the punching bag - extremely high quality and a perfect alternative to the mass-produced nylon crap sold everywhere else with brand adverts plastered all over them. Lifetime guarantee is a great touch as well, though with the high build-quality I don't anticipate ever needing to cash that chip. Shipping was a lot quicker than expected as well.
One thing to note: does not come with any chains or mounting hardware. Not a problem if you're a remotely resourceful person who can handle fabricating what's needed and hang it yourself, so still 5 star for me, though some people may want to know ahead of time.
