This product turned out to be one of the best ratchet systems I have bought. And this screwdriver set is the first set I've ever bought on Amazon, and I'm pretty IMPRESSIVE on it. It contains 115 pieces in there, Each of the bits has its own individually labeled spot that has good grip and will hold onto the bits even if the case is inverted, which you'd use for repairing laptops, computers, watches, and iPhone or monitor. Besides, the set also comes with a magnetic pad if you organize your screws in little boxes. All I have to say is that it's been wonderful, and it exceeded my expectations, especially in the great quality.
