Don’t know if it’s just mine or all are like this but the light has 3 lenses on the end one for each type of light

Black light works totally fine no leaking through other lenses which is why i don’t think mine is working as intended and there is a defect between laser and flashlight

However for the overall function and price of the device i highly recommend and would buy aga

Switch on laser is way better than push and hold down buttons i’ve had in past
