I'm not a picky person, & I'll always try to make the best of a bad deal; however, this wasn't worth the hassle.  Unless you actually have experience using this tool DO NOT PURCHASE IT!!  My set arrived with all the bit pieces scattered in the container & worst of all NO INSTRUCTIONS!! So, luckily Amazon has a decent return policy & I didn't have to suffer a bad deal, along with the cost for Shipping & Handling.
