I love this bag, and it was exactly what I was looking for. It is heavy, didn't require installation, doesn't shake my house when I want to box in my basement during naptime (like hanging bags do), and provides both kicking and punching room. I love the scoring zones, which I use as targets for different kicks and punches. It wasn't that difficult to fill. It's the right ratio of firm-to-soft for me to use with various glove thicknesses.
One slight downfall (which doesn't make me love it less but is true to other reviews) is this: I am a moderately strong, 5'1" girl, and I can push this thing around if I beat it too hard. Even after filling it to capacity with sand, I had to place it on a non-slip pad AND back it up against a pole in the basement to keep it from sliding around. Just something to consider. Personally, I love it, it does what I wanted it for, and I would definitely purchase this again.
For those interested, if you Google this item, there is a website that cells a DVD with workouts for this particular bag.
