Perfect addition to the home gym. Purchased the set, 12, 18 and 24. Easy to put together, didn't have any issues with the holes or bolts like other folks had mentioned. The smell was extremely strong though from the rubber. I put them outside for a few days and it went away. It's a great addition for me to do my step ups, reverse hypers, abs, tons of ideas. Sturdy and love that it stacks. Would def purchase for someone as a gift for their home gym.
