Received it yesterday and had to try it - so after I put it together at home to learn, I went down to the place to canoe and went on a careful paddle even though it was windy and the water was choppy.
Stability isn't perfect but it's not bad - I didn't get the extra seat attachment, so it will be an adjustment to get used to where the center of gravity sits in this.
It feels like sit on top kayak but sitting up higher.
Legs got a bit tired in the positions possible- can't switch to kneeling with the seat in. More stable when sitting cross legged.
Used a kayak paddle. Got wet/water in the boat, but not a big deal.
The wind/sideways choppy waves felt a bit more thrilling than ideal - the material is very light. But it wasn't worse than a sit on top kayak.
It's not hard to put together but the folding makes some crunching noises that I hope don't mean it will wear out!
If it holds up well, this thing is going to be incredibly fun for my casual paddles. I don't have a roof rack or big vehicle, and I'll often go alone on short paddles without easy vehicle access, so this is really simple. Can't wait to take it to Lake Louise!!
I'm not sure this is the #1 item for a die-hard multi-day scary river kayak paddler or someone who wants the most serene canoe ride on earth. But if you want something that isn't inflatable and just is tons of fun... as long as this is durable (time will tell), then woo. Wish the warranty was a little better after folding it a few times but I'll try to be gentle. This is a massive lifestyle upgrade for me.
Note: I shipped it to Calgary, Canada. Shipping was fast but customs broker fees & tax cost $147 CAD and that was a bit of a shock.
