Fine module, works well – Red Laser Module - Adjustable Crosshair (3.5V~4.5V 9mm 5mW) Reviews

Involvement:Expert (understands the inner workings) - Ownership:1 day to 1 week

Pros:
Fine bright laser crosshair from 3v upwards to 6v without any sign of overheating. Brightness varies very little over that voltage range. Strong metal body in easy to machine brass.
Cons:
Laser cross spreads very wide very fast. Easily remedied by adding a tube or anything to limit the beam spread. Focus cannot be adjusted.
Other:
Take great care if machining the laser body, it can be threaded for inserting into a panel but anything else is asking for trouble.
Bottomline:
Good module. Will almost certainly buy more.
