So my friends and I are looking to buy our first vape, and there are two on our local craigslist, both for $100 and both in excellent condition. They are the Vaporcannon 4g and the Vaporbrothers Box vaporizer. They look very similar, but I was wondering if there are any significant differences or if one was prefferred to the other by the community, because I haven't been able to find any comparisons of the two anywhere!
