Don't buy either of these. They are shitty! I had the one with the motor and it sucks. The motor barely moves it, and I had two break on me in one week. I went and ordered one made From Seadoo online and had it shipped to my U.S post office. It's way better quality and well worth the extra money.
I bought the Mega island, but my friend has the Aqua lounger 6 and it's just as nice just a little smaller. If you go to the lake often, these are well worth the money. I've used mine like five times, and it has paid for itself. Although, I took it to Kits beach and the beach patrol wouldn't let us use it as it took up too much room.
