I owe it to leave a practical review here based on the ownership on TWO of these Jet Bob's. The problem with Jet Bob is the complexity of the design. Jet Bob has inner chambers and seams that when inflated create the cute form. It's these chambers and seams that fail pretty rapidly once under stress behind the boat. The first Jet bob lasted one ride. The inner chamber tore from the inner surface making one side bulge and unstable. That was after a 20 minute ride. I returned it for replacement. The second Jet Bob split on the underside seam almost immediately. It was patched only to have the other under seam fail. This was also patched but once out in the wake the seam split ran to a 17" well beyond any patch available on the market. I cut up a Coleman mattress as patching material but due to the outward air pressure such a seam can't be fixed. I plan to patch on the inside and outside and hope for the best. Sevylor wasn't helpful only to suggest a hardware store for glue. This is catastrophic failure on a basically once used Jet Bob! The underside of jet bob inflates to create a pleasant slipstream form but puts the 6 mm seams under great stress. The form is unnecessary since it is covered with the exterior nylon sleeve. . Had the form been simpler fewer seams would be necessary. Do not buy Jet Bob unless you love glue and patches and lots of disappointment whilst boating with the kids. Keep it simple and buy a flat towable and enjoy lots of summer fun. I'll be glueing and patching trying to get my money's worth.

• How accurate was the sizing? very
• Please tell us about the quality of the product. High Quality prone to failure beyond repair
• Was the product free of any manufacturer defects? yes - but over design leads to seam failure

Great fun for the kids, we can fit 2 or 3 kids on at a time and they love riding on this. It is very stable. Great tube for the price!

Purchased this for our grandchildren. Was very impressed with the quality and compared to other towable items, could not beat the price. It was definitely a great buy.
