This tape works perfectly for my label maker and is cheaper than the other brandokIt works very nicely in the required measurements that i use. Would recommend.These are great, and much better priceThey work. Labels have stuck, no adhesion issues. Worked as expected.I just purchased a Brother P-900. Wasn't sure about these off-brand label cartridges but they've worked beautifully.I've used them to organize my supplies for my K9 nosework students. And to label the tins & lip balm tubes we use to hide odor in for the dogs to find. They now look very professional when I mail them out to students.Unlike ink jet printer labels I've used in the past, the ink doesn't rub away when the student holds these with slimy dog treats and get wet with dog slobber.I've only had trouble with one colored cartridge (same brand but from a different purchase here on Amazon). It's ribbon broke almost immediately upon trying to use it. Can't see how it can be repaired.But the others have worked very well.These are such a good value and the print and adhesive quality are just as good. I never inspected the other labels other than can I read them, and I can read these.No issue with compatibility in my label maker.These printed, adhered and looked arguably better than the Brother brand name ones.Gracias
