Looks annoyingly bulky to me. Smell isn't bad - stick hand in bag, grab poop, invert, knot, hook knot between fingers of leash-hand so you keep a hand free. Pitch in the next bin you see. If you're smelling it, walk faster. ;)

I'll loosely tie and reuse one bag on the same walk as long as it's not too full. Can manage two leashes and three or so bags just fine with one hand, though, so mostly just a trick to delay refilling the bag dispenser.
