## Before you buy

- The listing gives conflicting weight information: a feature claim says under 6 oz, while item details list 1.56 pounds. It also describes the six-size kit but does not provide an explicit package inventory, so confirm the delivered contents and tool weight in the selected listing.

## A good fit for

- Fiber installation technicians handling multiple microduct diameters on a job site.
- Buyers who want interchangeable cartridges and a tethering point for confined or elevated work.

## Less suited to

- Buyers who need a confirmed tool-only weight or a definitive package contents list before purchase.

## Frequently asked questions

The listing names 7 mm, 10 mm, 12 mm, 14 mm, 16 mm, and 20 mm diameters.
### How many cartridges are included?
The feature claims state that three magnetic cartridges are included. The page does not provide a separate explicit package inventory, so confirm the selected listing's contents.
