Query: Good product - pump is useless

As advertised. I am 6'2" and this is perfect for me for use at my desk (I like to sit a little high).Seems like a quality product and black is less obtrusive for the office.Shipping was quick.Included pump was a complete waste of time. After pumping for about 30minutes I gave up and just blew it up myself which was pretty easy. Note that you'll need decent lung capacity or a better airpump to get anywhere near the (max) 75cm diameter. I found that after a few days of sitting on it and topping up the air as it stretched out I could get it to the 75cm max (which is pretty firm).
