Review on 🥊 Pro Impact Authentic Leather Double-End Boxing Punching Bag - Speed & Dodge Training Ball Set - Includes Cords & Hooks for Gym Workout, MMA, Muay Thai by Andre Motko

The bag itself seems fine but the bungee is not what I expected. One of them broke so that it almost broke in half. They are also made of rubber material instead of the usual bungee material. I ended up having to spend more and get the right attachments myself. Although the bag itself looks decent. I don't think you can replace a bladder based on its design. If you just want a decent leather bag that's better than, say, a timeless entry-level version, then this would be a good choice. If you want something with interchangeable construction and possibly longer, spend a little more and maybe get the title brand.
