I purchased one of these for outdoor MMA training and was blown away by the size, I thought for sure it would take forever to inflate but it was super fast! Overall I'm very happy with my purchase, I actually really like the size, the length allows me to do much more movement then I expected I would be able to do. A few of my buddies from MMA class come over on occasion to use it and they all love it. Very surprised and love it! :)
