Runs very well, first 3 days didn't open or stretch, then we started cleaning and replacing the ceiling panels Lots of dust and dirt in the air at work and before me clothes and Belts have slipped a bit but are easy to grab and adjust as they are very well made. Where some straps (because I have a size 4 belly) form an X sort of thing or are misaligned, this strap is strong and thick so the ends and velcro are easy to align. This is now my favorite belt so here it is.
