I purchased the Advanced Elements Advanced Frame Elite Convertible as a joint Christmas present for my partner and I. So far we've had it out both at the beach and on the Murray. It's been easy to set up and the pumping isn't too bad given its size. Both my partner (6'1"), and I find it comfortable and spacious in solo or tandem mode. It even fits easily back into its bag with all the accessories AND the addition of a pump to make the kit complete. The only change I'd make would be to add a foot rest for the front/solo paddler similar to what the rear paddler has.
Emily was very helpful with a follow up call when she realised I'd made an error in my order.
I'd highly recommend both the kayak and Oz Inflatables.
