Me and my stepfather bought 2 thinking it would be a great way to keep fit and have fun. was fun but it was so much effort getting the things to the water we ended up selling them. cost a fair bit too. if its something to just fill time i would say try something else. a 59inch led tv, a ps3 and a fridge full of beer would be a good start. if you need a mate to share it with I will volunteer my services
