The build quality is really good and it does make getting your kayak up on the roof of your vehicle easier but trying to get my kayak sitting on the supports is not possible, it's a Sit On Top style kayak (very common) and given the shape of the underside of this kayak it doesn't sit on the supports legs the way the instructions recommend it should. I'm sure my other kayak will be fine (Sit In) as the shape is different. For this sort of money, ideally this system needs to come with different shaped support legs for different shaped kayaks.
