I must admit, you do have to have a steady hand to zap the pests.
But the 445nm (blue) laser diodes all need to be focused, so nothing around the area usually gets zapped, until you get a night tight dot on it.
This focusable diode makes it possible to pass through glass with minimal intensity loss. just watch out for the reflection, bc sometimes it can be on your hand, and you wont notice
Acrylic is still up for debate, but all personal experience in the additional videos done by tome, show no adverse effects, or scores on acrylic.
