This past week we heard a large "crash" and our kayaks fell to the floor.

Mounting went pretty easy and then the mounting bolts broke and my kayak crashed to ground

I wouldn't trust this as delivered at all , as the flaw is hidden once you install it and will be uncovered only when your kayak or canoe is someday crashing to the floor after the rope fails at this point.

works as it was advertised

Only 4 stars as the company shouldn't include any lag screws and should require the purchaser to buy the appropriate rated screws for mounting as the included screws for my application were too short and some were very poor quality as they broke.

This thing is as great as it is simple.

A little tricky to orient and run the rope but works as it should.

Notes: It MUST be attached through the ceiling to a strong beam(s), so accurately locating that beam is essential
