16120 Focusable 648nm 650nm Red LINE Generator Diode Red line Laser Module Laser Level for Sawmill Machine Alignment + Mount+ Adapter

Let me start by saying that it's doubtful that this is 100mW. More like 5-10mW at best! This kit comes with a red laser, generic mount with screws and wall anchors, Allen wrench and a power supply. The mount is basic and will work in light duty situations but it does not appear to be very practical for most uses. The laser has a focus ring that allows you to focus the line it produces which is ok but not as fine as I would have liked. The title states 648nm 650nm, this is a 650nm and is not selectable, not sure if that's a typo or they were not sure which it was. My guess, it was a typo! Considering there are no other level indicators mounted to the unit or other means to reference when the line is level it is not well suited for any type of construction or measurement reference. This is more suited for a beginner hobbyist or for experimenting with lasers as a learning tool. The 30-35 dollar price range and the minimal power output sets this in the category of an over-priced toy for experimentation or fun.

Worked great for my project

Very good
