In the last few years we've printed well over 250,000 mailing labels on these labels and had very few problems with them. In fact, I'd say that the problems we've had have been from user error when the labels got off track. When installed correctly and allowed to feed straight out (not cocked off to the side) we have absolutely no problems with them. They stick to the boxes well and travel the distance without any problems. Sure, they may be thinner than the name brand labels, but they get the job done well, without exception, for a whole lot less money. That's a big win for us.
