If you or your family is anything like ours, you have had some tool, toy, electronic device or other that has required a precision tool. Well, look no further! I am so impressed with this set! Let me say, the Royace Precision Set is a dream come true! This set has over 115 bits and more extras that will definitely come in handy. The convenience of the double-sided case clips closed to keep everything contained in one organized place. Each bit is clearly labeled so it takes out the guesswork. This is a quality feeling set that seemingly has more bells and whistles than I will ever need but I love the security of knowing I am prepared. From small electronic repairs to simply opening the battery compartment on a kid's toy, this set should do the job!
