Purchased to remove mastic and hardener in bedroom/master bathroom. This tool really saved me time and money removing the adhesive used to attach the flooring. Before purchasing I tried using some sort of adhesive remover made specifically for flooring from a big store, which didn't work that well and easily cost me a few hundred dollars or more to maintain and then dispose of. Thanks to this tool, I was able to finish the entire room in a few hours. When I later removed the tiles in the master bath with a bulldog, I was able to use this tool to level the floor again after removing the tiles. It easily accepted the flimsy set used to lay tiles. If I had any complaints, the blade could get hot after prolonged use and the bolts/locknuts that hold the blade in place could lose vibration. This has happened to me once or twice, but I was able to easily re-tighten them and get back to work.
