Great More than I expected
It did exactly what I bought it for and that was too going done into cured resin and hollow out some mistake areas. Very powerful, lightweight. It took me a bit to figure out how to tighten the bits, but once I figure out you need to lock it while you twist, all was good. Can't wait to use it for other things! It opens up a whole other world of creativity
