This is a FANTASTIC budget friendly way to get your punches, kicks, elbows, knees in, etc. We have limited space and this bag is thinner than others on the market but that is a great thing as it is easy to move around a room if you need to store it away each time. I am not a fighter but I spent years in an MMA gym daily mostly with Muay Thai hitting heavy duty bags, etc. My teen son wanted to get into bag work and I saw this and the good reviews and was immediately blown away. I got him this as a Xmas gift and he was surprised. The quality of the bag is very good and even with just water it is heavy enough for most people. If you are an extremely hard hitter, sand is your friend and the spring base will come into play. I can throw a solid hook and this thing along with the gloves hold up very well (with wraps on of course). It will even hold up to muay thai kicks for most people. Highly recommend this.
