The bag did not fill entirely at first, I thought oh well, for the price, it's still usable. Left it on the side for a few days, when I picked it up again, I was surprised it pumped up more to rock hard. I put the bag down again and for a few days it held the air. One week later, the bag is still rock hard, pretty amazing product.

Perfect for my cheap Century speed bag that was leaky from day 1. Unlike my vintage Everlast bags, the Century was not designed for ease of bladder replacement, but hats off to Forza for making a strong and flexible replacement bladder that I managed to work in place, glue around the valve stem, and line up the valve hole, not perfectly but adequately.I chuckled at the description saying low cost enough to keep 2 or 3 extras for emergencies because I thought I was the only one who would consider a leaky speed bag an emergency, so I might just do that because these bladders are of the quality to merit use on my high value 1970s vintage Everlast bags if such an emergency arises.

Be nice if it had stick on near the air valve so it would fixate in the bag

Top notch quality speed bag. The leather smell of the bag permeates throughout my garage. Purchased the extra small for speed a little getting used to for my tricks. Due to the very small hitting area of this 5x8 bag you need to be very precise. Getting ready to purchase the 6x9…..this is a superior speed bag!!!
