I bought 10 of the fitness pods of various weights for my Combatives Gym, Modernize My Fight. They have a great feel. You can smash elbows or hammers and the pods just have the right amount of give and can take the abuse easily. The handles take a bit of getting used to when doing drills such as around the worlds but you very quickly forget they are there. They are a bit to light for my taste for doing knees drills standing up but that is a very minor point. What I was most surprised at was how much Liked using the 18 pound version. I am 290 pounds and just assumed the 35 pound pod was the only one I should use. Using the 18 pound pod the pod "squirms" underneath me creating a sensation of working with a live partner. The 35 pound stays more in place and is good for when I really want to get aggressive in my strikes. This was a great investment for my gym.
