Built from durable aviation aluminum alloy, this flashlight is water-resistant and drop-resistant, capable of handling rough outdoor conditions or accidental falls. Its compact size and anti-slip handle make it easy to hold and operate, even with gloves on.

This sturdy and multifunctional flashlight may be a bit heavier than simpler models at over 13 ounces, which might be noticeable during long use. It suits pet owners who need a reliable, long-lasting tool not only for urine detection but also for outdoor activities and emergencies, offering good value with its dual light modes and solid build.
