A little shallower than I wanted ( I wish I had bought the 18' x 42"), but otherwise a great little pool. My kids loved it this summer and we only had a few minor glitches. The pump is a little trooper. It was used to fill the pool from a creek as well as being allowed to run up to 3 days straight (oops).  One "glitch" - my kids let some of the air out of the upper ring. No one was in the pool and I just happened to remain outside. The water suddenly began flowing over the ring, pushing the side down - it was a problem that would have resulted in losing all of the water (and causing a flood in our basement as we have poor drainage), if I hadn't been there to hear the sudden rushing of water.  For the price just lasting this one summer makes it worth it.
