I have been using these refill cartridges for several years. I have never had a problem with Xyron like I have with other tape runners. For example, the tape never moves from side to side along the roller. It does a good job next to the straight edge of the card or page you are gluing something. The tape is very sticky and there is not much danger of the item falling off. I would certainly recommend this product for your Xyron Mega Runner.
