Based on my observations, this precision screwdriver is perfect for fixing small items like eyeglasses, phones, and watches. The fine-tipped screwdriver heads enable you to handle even the most delicate jobs with ease. What's more, the non-slip handle provides better control making repairs more manageable. The only downside is that the set doesn't include a case or a storage bag, so you must find your own container to keep the tools organized. .See full review
