I measure designs for life. All day, outside, in any weather, in any conditions. I have burned dozens of cassettes of all brands over the years and this is the only one I will ever order. It's also fully repairable - as no tape going through mud/sand/water/snow/dung lasts forever - I appreciate being able to just replace the tape. The loop closure is safe and secure, never falls off. I get in and out of my truck a hundred times a day and it stays buckled the entire time, flexes slightly up and out of the way when I get in, and the hook folds down so it doesn't rip my seats. My business mentors have used the same tape measure for decades, going back to Spencer Logging tapes.
