Makes good labels.
These labels stick well and last without fading when indoors. Put clear packing tape over them and the harshest of cleaners won't effect them.

Great labels - 100x better than the generics
These are the way to go. Don't mess with generics and knockoffs that are 10 bucks less. It's not worth it; they may even appear to work at first, but after a year, the cartridge won't feed. These can sit on a shelf in the label maker for years and still fire off a perfect label that sticks forever on the first try. Every aspect of these is higher quality than the generics. Genuine Brady all the way for me now!

Tape is very good but item is overpriced
This is a great product and works good. For many applications the quality of tape is really good. It's holds up for labeling cat6 cables much better than other types of tape I've used. Like everything else these days, the cartridges are overpriced. Looking into other products at this point for the applications I'm encountering in the field.

Genuine OEM cartridge very reliable
I recently purchased a Brady M210 label maker. I used it on a large project that required labeling dozens of cables. These OEM replacement cartridges are pricy, but work great. No unexpected issues. The product arrived in excellent condition in a bubble protected envelops. The .75" wide label stock is perfect for descriptive abbreviations when printing in wire marking mode. The .5" doesn't have much room for descriptive wire marking, but does fine for lengthwise banner marking. The cartridges are very easy to install. However, the only trouble I had was my own lack of experience with the equipment. Be sure the label stock fits properly between the two small plastic guide clips at the end of the cartridge where it feeds out to the labeler. Otherwise, the label stock won't advance properly and jams before exiting the labeler.

Great labels!
I have been using these for about 20 years, IMHO they are the best! Getting expensive, but worth it! I only use the nylon cloth type.

Works great and neat for nice labels
GPT Title: Superior Durability: Brady Authentic M21-750-499 Nylon Labels Review: I recently purchased the Brady Authentic M21-750-499 Nylon Labels and I couldn't be happier with my choice. These labels are truly multi-purpose, making them perfect for general identification, wire marking, and lab applications. The black text on the labels is bold and clear, ensuring visibility and readability across all uses. What impressed me most was the durability of the nylon material; it holds up excellently against moisture, abrasion, and varying temperatures, which is crucial for both indoor and outdoor applications. They adhere well to surfaces without peeling off, making them reliable and efficient for organizing and marking. A solid 5-star rating from me for these outstanding labels!
