opinions about the time saving factor are correct. We are in the process of making our own 1700 square foot laminate floor and this tool is great for speeding up the process. I can confirm that this replaces using the hammer and block. You just use your wrist to firmly block the boards and it works like a charm. It really is one of those products that lives up to the 'game changer' title as some reviewers call it. I do not regret this purchase!
