The product was great. Inexpensive but worked like a charm to remove floor tiles and the thick layer underneath. Short learning curve - when removing a tile you need a shallow angle of about 15 degrees but a steep angle of about 65 degrees to remove a thin layer. Used with an old Bosch Bulldog and worked quickly for about 3 hours on 300 square feet. Unbelievable! I waited several days with much swearing and calluses. Glad to hear about it.
