I am a huge fan of these...so much so, that during the recent Black Friday sale, I picked up a third! I use them on all my bags and since you can attach the tab to almost anything that you need quick access to, they change your EDC. I use this on my Flight Tote M to attach a EDC medical pouch that I made using one of the Zip Pouches with hook and loop (the patches are the 9th Anni). It's so great and means that quickly I can access things like pain killers and other essential without digging in my bag or having to open it. The other best part because I'm a fan of the Hub Ecosystem, I have the caribiners on other bags which makes it so easy to swap out pouches etc. when I want to switch bags - and depending on my needs. If you're wondering, the magnet is very strong.
