Bought this a month or so ago but, with the usual British summer weather, we've only just started using it.
It seems quite well made and is quite easy to inflate, although there are a number of different types of valves on the kayak. The ones on the seats and the splash covers don't have seals on the valves to stop the air coming out while your inflating them so you have to be very quick getting the cap onto the valve when they're fully inflated.
The extras we bought for this were the paddles and the Sevylor pump, which is very effective. We didn't buy the skeg which others recommend but found we didn't need it. I'm not experienced with a kayak but didn't have any problems controlling it so I wont bother purchasing the skeg.
It is quite heavy to carry, even with the rudimentary straps, but hopefully that means the material is a reasonable thickness.
I'm not sure I'd want to use this for two adults as it would be a tight squeeze, but for myself and one child it's a good size.
I'd certainly recommend this but, as I've said, I'm not a kayak expert so don't have anything to compare it against except cheaper plastic dinghies.
