Just got my hands on this 4D 16-line laser level, and wow—it’s insanely bright! The red beams are visible even in direct sunlight, which is a huge plus for outdoor work. The adjustable brightness (long-press V/H) lets me fine-tune the lines depending on the job. Burst flash mode (short-press OUT) is a lifesaver for harsh light conditions.

The 360° coverage is unreal—two horizontal and two vertical planes mean I can map floors, walls, and ceilings without moving the device. Perfect for tile work or hanging shelves. Battery life? A solid 8 hours, and the digital display keeps me from guessing when to recharge.

Love the pulse mode for outdoor use (brightness doubles!), and the tilt function is clutch for angled projects. The magnetic base + swivel lets me stick it to metal surfaces or tripods, and the removable laser window is a nice touch for maintenance.

Best feature? Hand-wave control! No smudging the device—just wave to switch modes. Check my video demo if you don’t believe me. For $100-ish, this thing outperforms models twice the price. 10/10 would buy again.
