IMO,there not really worth it,i got a zig zag one for £1 and its was a waste of money!
they take up too much time its better just learnin to roll

they arnt really that bad. i use them for my cigarettes they are really pretty good, but they arnt for joints..joints need to be handrolled or they arnt really a joint to me and besides using a roller for a joint is lazy...way to lazy
