get the real bubblebags if u can, the quality is much superior to the others out there.
ofcourse if u are on some kinda budget u might wanna try the cheap ones 1st but im sure if u tried the real bubblebags side by side with any of the cheaper versions u will see how much better thay really are and maybe save your dried trim till u can afford the bubblebags as apposed to the bubblesacs.
