"SQUEEZY" and "PULLY" that is the deck building duo names for my wife and I.  We reconditioned our large deck with all new 16ft boards.  This tool was awesome.  We have super straight boards now and it looks fabulous...darling.  I have no suggested design changes nor do I have anything really negative to say about it.  It works exactly as I had hoped.  So when she and I worked together using this tool, we primarily used it for squeezy work pushing the loose board closer to the previously secured board. I would recommend this to anyone who needs to install deck boards.  It is not as easy to use by 1 person as I read in an earlier review.
