I liked the idea of an attached to the belt suspender. These are OK. The problem is that I carry heavy junk in my pockets all day at work. These are elastic. That does not hold up to around 5 pounds of junk. I can't carry my toolbag because that adds to around 8 pounds and destroys my shoulders. I'm on the job and on the move for 12 hours at a time. I only need about 20% of my tools on any given day so I got a Maxpedition(medium) drop pouch to carry my typical junk in. I also have a 5.11 nylon belt and I carry a Swisstool and LED Maglite on the belt. All of that weight is heavy on the hips so I thought, "Why not get a set of suspenders to lighten the load and keep the pants up?".
  These do help lighten my load. They also keep my -unloaded- pants up. I got elastic because I get on the floor quite often and I was worried that a more static suspender would simply fall off all the time. This is probably going to be the case since even when I cinch these down pretty good the one side slips a bit after a couple of hours.
  I can say that if you find yourself constantly pulling up your pants then these will serve you well. Don't expect them to carry more than about 3 pounds of pocket junk(too much, I know, but I can't part with most of it). Also, if for whatever reason you need to hit the john, you will need to completely remove these beforehand. Elsewise, for a regular daily usage type of person these would be just fine. They are really easy to attach and they stay that way.
