Suitable for roughly a 6 inch figure. Haven't tried anything bigger but I doubt the telescopic lock could handle too much more weight. Surprisingly the suction cups work rather well as long as you apply enough pressure to get them stuck on properly. I currently have figures suspended from the top of my glass display cabinet and they don't look like they are in any risk of falling. My only gripe is that you can't have a figure perfectly vertical in orientation. Due to the connection parts having grooves rather than being cylindrical where they connect (which does prevent heavy figures just rotating under their own weight) and how they decided to place the grooves, it means that your figure has to be on an angle. So as long as you want a flying or spinning pose it's fine. But you can't have that classic Superman or Dragonball Z pose where the character has just levitated straight up which is a shame.
