IMHO the poparrzi is a pos and an expensive one at that. Here is my review of it on yjb which I originally post in September 2011.
""I have had this tube out several times already, on a scale of 1 to 5 I rate it a 4 from a rider perspective and a 3 from a drivers/towers perspective.
Pros are that it holds 3 riders, has lots of handles and a unique shape which allows riders to kneel, sit, stand and lay on it. It is also great as a lounger since the arch makes a great sun shade. Despite it's large size it takes little time to inflate and deflate.
Cons are that in the seated position the are are no back rests, it tends to roll and sit side ways once it gets unbalanced due to rider movement (which for me meant pulling the tube and riders in to the swim platform to reset everything), it is very hard to control with the boat once it gets side ways as well, the arch is not rigid so its usefulness as a steering tool and/or leaning mechanism is very limited. This thing is big and heavy, it takes up an entire under seat storage compartment in the cockpit and weighs 65 lbs dry.
Cost: List price is just under $400 but 25% off coupons are available online and basic shipping can be had for about $20.
Recommendation: This is a good tube for families/kids that don't want to go very fast or turn often or hard. If you are looking for a multi person towable that can handle more speed and turns but which is also comfortable for riders and is easier to control while towing, look elsewhere (e.g. The Connelly GT3 or 4)."
If you want a big 3 or four person tube at a great price check out what costco is pushing. This year it is a 3 person model, the last few year it was a 4 person tube. Every year it comes in a kit with at least a properly sized/gauged tow rope. This year the included an electric air pump as well for just $220. The return policy can't be best. I've returned, actually exchanged several, without a receipt or box and usually without the rope either. I got full store credit every time, no questions other than what is and about when did I buy it. Here are pics of what my local costco was pushing this year for $220.
