Are cheap sub-$30 laser measures accurate enough for DIY?

Verified-purchase reviewers say budget units from brands like MiLESEEY and RockSeed are accurate enough for DIY measuring of rooms, flooring, and furniture placement. However, specialist-community threads flag inconsistent quality control, occasional out-of-tolerance units, and short red-laser visibility outdoors. For professional use, most trade reviewers steer toward Bosch, Leica, or Klein.
