Each piece fits together with a hex connector and is magnetized so they easily and quickly snap into place. All of the bits are color coded and organized by type. I almost didn't order this set, but I'm so glad I did. I highly recommend it for quick tool access for menial jobs around the house or even for more skilled tasks.

This little pack has saved me a bunch of time so far. It is so easy to use and the amount of different bits you get, It is unlike anything I’ve seen. The carrying case is a nice touch as I can keep everything organized and together for future use. The value on this is unheard of, and I recommend this product to anyone that uses tools around the house.

I am so glad I ordered this. I just built a new pc from scratch and it was so easy to use the ratchet feature to screw everything in. The modular aspect of this set helped a ton, as well. This is WAY worth the price. As someone who uses handheld screwdrivers a lot, this saves a lot of twisting of my wrists and makes my life SO much easier.
