What Customers Are Saying

Customers overwhelmingly praise this post level for its hands-free strap design that eliminates repositioning and enables one-person operation, freeing both hands for holding posts or pouring concrete. The cross-check vial delivers accurate alignment in both directions, dramatically reducing time compared to traditional levels and transforming two-person jobs into solo tasks. Most describe it as sturdy and durable for the price, with reliable performance across square and round posts. A few mention the elastic strap could be stronger, and rare reports note inconsistent readings, but these concerns are vastly outweighed by widespread satisfaction. Overall, reviewers consider it indispensable for fence and mailbox installations.

Good grip

Would Recommend

My posts are plumb, so the accuracy appears to be good. The rubber band that holds it to a pole is long enough for a 3” round post, but can also grip a 1 5/8” if you tie a knot in it.

Saves half the time in leveling a post.

Would Recommend

I got one two weeks ago. All in all its a great product for the price. One exception though.... the rubber b and needs to be more durable. It broke after I put it on the 4th post. All in all it helped do the job.

So simple

Excellent product, so simple to use, saves lots of time and frustration over traditional ways to plumb posts. Perfectly accurate when I checked with a level on two sides.
