I received my 1 Watt Laser on Sept 20/10



Opening the Package



The Laser arrived in a neat black gift box complete with charger and Safety Glasses

and Everything was nicely wrapped up in bubble plastic.

So no change of it getting damaged in transport

Instruction Sheet



A clear instruction sheet is provided with the laser.

Showing how to insert the batteries

A caution is also shown that inserting the batteries in the wrong way will damage the laser driver. So be warned



The Host



The host is a perfectly machined part.

All the parts screw in correctly and there a no metal shavings on any of the screw threads

Also the clicky switch feels solid and works perfectly every time.

It seems the adjustable lens is installed from the inside of the front

of the host and the focus knob is epoxied to the protruding lens

housing. Then the Laser and Driver get screwed in from the rear of

the front host section locking the Lens assembly in place.

The lens and front window are not removable without unscrewing

the LD/Driver assembly...



There is a 6 months manufacturers guarantee on the laser so that should be ok



The specified batteries fit loosely in the host... but do not rattle..

The host inside diameter was 0.753 and the batteries outside diameter

is 0.650....



Tested Specs



The tests were done with my lm10 thermopile and multimeter.
