I used some Dollar Tree markers. All I had to do was take apart the marker and stick it into the tubes and it worked. I just got a bunch of crayola markers from one of my son's friends and I did the same thing with them to another Berserker and the performance was sad. At first I thought that the Berserker was bad but when I put the Dollar Tree marker tubes in it works great like it should. I also took a drill and drilled out the ridges on the inside of the crayola markers and it helped some but not much.
Does anyone have any ideas as to what I am doing wrong, or what else I need to do to make it work with the crayola markers?
Thanks
