At five volts, this thing projects a discernible dot about 1 1/2 feet in a normally lit room. I need something to throw a bright dot about 20 feet. Junk in my book and it’s going back.

I only hooked it up to 3.3v battery. It was very satisfying.I'm happy with my purchase

It works great it's visible in air at night,it doesn't need a lot of power to work, but the weird part is that when you use something like 5v It looks dimmer so I'm using 3v.

using for a laser spirograph project - it looks good and works for what i wanted but specs say Working Votlage:DC3-4.2V - really don't get much brightness out of it until around 6-6.5v

I bought 3 of these in the same cart, because I needed blue lasers for my project. They sent me two of the pictured item, and one of much smaller form factor(like the width of a pencil eraser), and it wasn't even blue. It was red. Blue lasers don't seem to be prevelant and cheap at the same time, so I had to intiate an exchange, which with Amazon's structure, is making me now send back the item, kinda wasting my time, and inconveniencing me.Rather annoying, but so far they seem like they'll do the job for me. The lens does allow focusing, but I haven't tested the distance range with a fine dot yet.
