The most important factor in installing the product is which type of locking system does it incorporate. I am an old installer myself and I purchase only materials that have easy to use and precision fit locking systems. There are several different types available. The better quality ones cost us more. We pay the patent fees required to obtain these materials. Most stores dont pay these fees and subsequently sell inferior and sometimes outdated systems. When you are down on your hands and knees trying to get these materials to go together this becomes a very important issue to you very quickly. When you have a day of installing a poorly designed locking system and or product , you will feel like you have been in a fistfight and lost. The tools needed are minimal. The best thing we can offer our customers is free advice from a master laminate flooring mechanic. If you need help please call me . That is what I am here for.
