Our 14' Airzone that I bought many years ago finally broke apart so we decided to purchase this larger one for our 9 and 13 year olds. They really enjoy the larger size, and the only reason I didn't give it 5 is because they said the Airzone was a little more bouncy. This manufacture has ALOT of springs which are tighter than than the Airzone which may loosen up after more use. Also construction of this manufacture was much more detailed and took much longer, but it seems to be very good construction which should last. Other reviews are correct when they say read over the directions of both the manufacture and the net first before starting. I told my husband this and of course he didn't. He had to go back and take springs off to attach the net. This added another 30-45 mins to the construction.
