The BLACK+DECKER BDL220S is a compact line laser designed for indoor DIY tasks like hanging pictures, featuring a 360-degree rotating wall attachment.

Professional reviewers acknowledge the tool's utility for basic DIY hanging tasks but strongly criticize the 'self-leveling' label as deceptive because the device lacks a pendulum.
Everyday users generally find the device simple and effective for hanging decor, but recurring complaints focus on the misleading 'self-leveling' marketing and short range.
Sources lack independent expert reviews from professional publications. Manufacturer and retailer descriptions emphasize the tool's brightness, toughness, and accuracy, positioning it as a must-have for tool bags with roll-cage-like protection.
