I was looking forward to no tool drill but received the "Item May Vary" model with the same part number. With small hole saws, the drill bits simply screw in and once you've drilled the hole you need channel locks to take it apart. And big drill bits are the old model where you screw the pins into the hole saw instead of moving the pins up and down. Not that convenient. Also, the 7/8 inch saw doesn't fit in the case so it gets thrown into the spot under the auger which rattles there. And the casing is very thin and crispy. Ready to crack if you close it wrong. It works and the price difference between this and the Milwaukee is about $35 which you can use to buy the drills you should have received.
