This tube is a great concept, however, we did not have good luck with the durability of the tube. We got the first tube and it lasted about 4 hours before the seam blew out and it deflated. We called Amazon and they immediately sent a replacement. The second tube lasted about 1 day and a half before it blew out at the seam also. We returned the tube and were given a refund. The tube was a lot of fun while it lasted. The kids really enjoyed riding together. Thanks to Amazon for the great customer service.
