What to know before buying

Listing details to confirm

Listing details are inconsistent about the included bits: the explicit contents list gives 18 one-inch bits, while the product description later says six one-inch bits. Confirm the selected listing's kit contents before buying. The manufacturer also does not include a wall adapter, and the compact-length claim is distinct from the listed overall dimensions.
