Pros
  • Feels closest to a fixed dumbbell, with flat heads and a knurled aluminum handle
  • Twist-handle changes rank among the fastest in the category
  • Wide 5–80 lb range in even 5-lb steps
  • Five uses in one set: dumbbells, barbell, kettlebells, push-up stands and plates
  • Very affordable at about $85 for the 45-lb set
  • Comfortable grips and secure threaded collars, according to reviewers
Cons
  • Premium price: about $769 for the 80-lb pair
  • Plastic internal parts are the known weak point; not drop-safe
  • 5-lb jumps are coarse for light isolation work
  • Slow weight changes because collars must be unscrewed
  • Sand-filled plates are bulky for the weight
  • Barbell mode is short and light compared with a real bar
