I used to suck my self at rolling joints but buying a machine won't help you get better lol. Use it when you're already too high to roll but other than that please, for me, practice. You'll eventually get better just like I did. Even if I did use over 30 joints to get it right lol! Don't get me wrong, there is nothing wrong with a rolling machine. But what if you are stranded some where or you're just some where and forgot your machine? It just feels better to know where ever you are you can roll a joint no matter what type of weed or papers you're using .
