## Before you buy

- The listing title specifies a 9-inch level, while its included-components text calls it a 9-inch 250 magnetic torpedo. Separately, the listed dimensions of 41L x 42W millimeters do not explain the stated 9-inch length. Confirm the selected listing's exact size and configuration before buying.

## In the box

- 9-inch 250 magnetic torpedo level (Included): The explicit components list names the level. The feature description also claims a B-tank valve key, but the component list does not name it, so verify whether it is included with the selected listing.

## A good fit for

- Tradespeople or DIY users who need a compact magnetic level for steel work or pipe positioning.
- Buyers who can use dual-sided plumb viewing, common-angle vials or the stated tank-valve key.

## Less suited to

- Anyone who needs a stated accuracy tolerance or wants consistent independent confirmation of durability and stability.

## Customer feedback

Customer feedback describes the level as functional on pipes and often praises magnetic strength, versatility and material quality. Feedback is mixed on durability, accuracy and stability, which matters if readings must be dependable over time. The listing provides no accuracy tolerance, so buyers needing a specified precision should look for one before choosing it. The aggregate ratings are mostly five-star, but they do not resolve those specific concerns.
- Positive themes: Customers describe it as working well on pipes and praise the magnetic hold.
- Positive themes: Feedback also appreciates its versatility and material quality.
- Mixed feedback: Customer feedback is mixed on durability, accuracy and level stability.

## Frequently asked questions

### Can this level attach to steel without being held?
The listing says its rare-earth magnets allow hands-free work on steel. The actual holding strength on a particular surface is not specified.
### What is the slope button for?
The listing describes an integrated 1.5° button for 1/4-inch-per-foot drainage and says its slight radius helps the level sit securely on pipe.
### Does it include a tank valve key?
The feature description says a B-tank valve key is provided for acetylene or B/MC tank valves. The supplied component list names only the level, so check the selected listing's package details.
### What size is the level?
The title calls it 9-inch, but the listed dimensions are 41L x 42W millimeters and the component description uses 9-inch 250 wording. Confirm the exact size before ordering.
