This screwdriver set is great for everything small. I has a wide variety of bits and small tools that help do lots of more specialized jobs. I have a slightly heart rate watch that uses a battery and has brackets to hold it in place. I can never find the right tool to take off the bracket so it is always more of a challenge to replace the battery. I have gotten so frustrated that I have taken the watch to a jeweler or a cell phone place just to get the battery replaced. Even if I walk in with the battery in hand it still costs for their time. This has already almost paid for itself. If you work on computers or like to tinker, I highly recommend this screwdriver set!
