I purchased similar sets like these from this Seller before and everyone wanted one of them. I gave away many sets of them and then I discovered these, which had different bits and etc and these were also a major hit. These are totally awesome and include many bits and other things that are just very hard to find. They are worth every single penny. I would highyly recommend these Mini Precision Screwdriver Sets to anyone that needs these types of screwdrivers and bits for work on small electronics and etc like laptops, tablets, smartphones and etc. These kits include just about everything you need to get the job done, for sure. I work on all types of things like computers, laptops, tablets, smartphones, TV's, game consoles and many other small appliances and electronics and these kits have every single thing I need to disasseble and reassemble them. Do not be fooled by competitors and imitation products out there, be sure you are purchasing these specific kits from these Sellers before checking out and you will not be dissatisfied, guaranteed! I will certainly be purchasing more in the very near future!
