Even though it allows the bag to hang relatively low, its presence still has to be taken into account when mounting and dismounting. I imagine it would be worse if the bag rode higher.
You do get two choices of rail on which to hang the saddle. And yes, it does make swinging a leg over somewhat different. In morning have never had a problem with that. End of day, yes in worst case the bike gets laid on ground to dismount. Some choose to mount over front of bike, doesn't feel good to me. Karrimor used to make accessory rails that stacked upwards and allowed the bag to mount even higher. Most do not have a saddle so high that there's any chance of carrying a Camper w/o some sort of lift.
Problem with Bagman is it is overstressed. Just a long lever from bag to mount. They have a decent lifespan but do succumb in end.
