I have used these tags for over a month now and they hold up very well to the abuse of the airline baggage system.  It's clearly a good idea to keep identification with your baggage but you have to balance that with the privacy a tag can provide.  These tags don't "pop open" during transit like some others; they keep closed unless you press the side button to open the information card.  I have had Swiss backpacks that had to be replaced for style and use reasons before they have ever come close to breaking apart.  I feel, made by the same company, these tags will hold up just as well based on their use so far.  I purchased the gray/black ones and they were sold and shipped by Amazon.com.
