*Full review below*Quality: 9/10The zipper that attaches the bag to the base is tough as nails, but I wish there were some snaps or something to back it up. If it ever broke, the bag would be useless. That's a really nitpicky complaint though. The odds of breaking that zipper are practically zero.Functionality: 8/10Tough, tall, and great for any kind of attack including takedowns. Slide it into a corner to avoid knocking it over.Design and Mobility: 10/10Unlike heavy standing bags with huge sand or water filled bases, this is great for upstairs apartments, wood floors, carpet, and closet storage.Worth the money? Heck yeah.Ok let's think about the design of this real quick. The base is a fancy sandbag that weighs around ninety pounds while the upper portion is basically a solid block of foam around six feet tall that's extremely light. If you're expecting this to feel like a heavy bag, you're going to be disappointed. It's still the best bag I've trained with though, and here's why.I'm a mid-twenties, 180 pound, male, Krav Maga enthusiast. While my punches aren't going to have the same force as a heavyweight boxer, they're not something you'd intentionally want to stand in front of if you can help it, and I needed a bag that could stand up to lots of punishment. However, I live in an upstairs studio apartment, so I can't hang a bag and I don't want to fill a big plastic base with sand or water and get it stuck up here, so a bag I could pull out and then put away was a must. This thing is perfect for that. When I want to do a heavy workout with lots of fast repetitive punches, knees, and kicks, I just slide the bag over into a corner so I wont knock it over. If I want to practice takedowns, ground attacks, or do punching sit ups, I slide it back into the middle of the room. Zipping the bag onto the base took about 45 seconds of awkward squeezing and pushing (would be easier with two people for sure) but other than that it's ready to use straight out of the box. The construction quality is top notch, and the thing looks downright sexy. You're not going to find a better made, or more versatile bag at this price.
