I have only used this bag for a month, however, this is the same type of bag that I use at the gym that I train at. I decided to get this bag because I was familiar with the brand and because it was an amazing price. I had looked into numerous other brands and had done searches across numerous different online websites looking for a bag that would fit my needs. I wanted the bag to be at least 55”, be 100lbs, not be too expensive, and ship filled. After looking at different websites, it became very clear that this bag was the best option. Other sites that I visited had bags that met my requirement but, would either have a more expensive base cost and/or have a more expensive shipping cost too. Given the price for the product, shipping, and quality of the bag, I don’t know why anyone would choose anything else.When I received this bag and unwrapped it, I was very impressed. The bag was filled very nicely, the stitching was flawless, and after numerous sessions, and months of prior experience using this same type of bag at the gym I train at, I could immediately tell that this bag can handle a beating. No matter what you throw at this bag, kicks, knees, punches, or elbows, this bag is going to survive. I have only experienced very minor cosmetic damages to part of the logo, which I really don’t care about because this product is literally meant to be beaten up. I am assuming that the damage is from glancing elbows because the logo looks smeared and I can’t imagine it being from anything else.Overall, I am very pleased with this product and I believe that anyone that decides to go with this bag will be pleased too.
