MaxxMMA Advanced Cobra Reflex Bag Kit 2.0 - Professional Boxing Training Equipment for Speed & Reflex - Perfect for Home Gym, Martial Arts Practice, and MMA Workouts

Excellent product for my needs and a lot of fun to use. Great workout.I’m not a heavy user, only one or two workouts per week, but it’s been perfect for me. It’s another bag that I can’t walk past without stopping to hit it a few time.Set up was easy. What took longest was filling the base with sand. The opening is very small and the sand backs up in the funnel constantly. Lots of tapping, poking, and shaking involved in the process. I read that sand is heavier so I went with that and got almost 50 lbs in the base. Then I filled large plastic bottles from the dollar store with sand and put them in the weight bag on top of the base. It’s very sturdy and doesn’t move.I saw people complain about hitting the edge of the plastic cup at the base of the bag. I wrapped mine with a foam weatherstripping from Lowe’s or Home Depot, then wrapped that with electrical tape. Easy to do and easy to replace when it wears out. It hasn’t come loose or worn out yet for me.So far, it’s been excellent for me and I feel like I’ve already gotten my money’s worth. Great fun. Great workout.
