The black k1 is doing great on calm water, it goes really fast. But when I took it to the beach, it was less stable when the wind and waves are strong. So that's one thing to be aware of. Overall I'm quite pleased.
Hit the water and had fun last weekend. Love the black color.
Just like what I read from other reviews, it took a little bit more time to get it ready for the first time. And then things get easier. It comes with a paddle. But I prefer my own paddle, which has better quality. Anyway, the reason I bought it is for its convenience and transportability. The color and shape are also cool to me.:D
The black one is the coolest among these kayaks. Love it!
