He already belonged to the basic equipment of the FEIN MultiMaster (I think anyway - is already a few years ago) and belongs with me to the top five most used attachments. What you should not forget, it's like most essays a consumable item. But the material is so good that you can scrape much (colors, carpet remnants, wallpaper and much more.). If necessary regrinding times short and he is almost like new. My conclusion: For me, a must-have for fine MultiMaster!
