Your review: We unload containers from JAX Port on a regular basis and this dock board works really well. We've been using it for about 3 weeks now and works well for our needs. We unload bulk bags that are strapped together and weigh a total of 4000 lbs. You have to have good support to keep them from falling over. This dock board has done the trick, so far.
Pros: Rigid and easy to move.
Cons: None that we have found.
