Got this pointer just recently and I've been impressed with how well it works and how sturdy it feels. My previous pointer broke within months of buying it. This one is mostly metal and feels like it's going to last.

This pointer gives a good feel of quality product. It's spot is bright, and its low divergens enables one to give a glance on the spot from ~200m with no problem. Note that the emerging beam is rectangular (it is probabply the emitter's shape), thus a "sinc" (sin(x)/x) pattern is expected at distant screen. Also, it is almost totally polarized, and can use for simple lab experiments with visible polarized light.
Overall: good Purchase.

I use the laser pointer during Power Point presentations. The portability allows me to walk around the room during a lecture. Presenting this way is more interactive for my students and is more professional than using the mouse to point-out important features on the slides or lecture board during my presentations.
