Damn, my Jet Laser PL-E Pro 520nm Diode Green Laser came in today and it apparently doesn't work. The 18650 batteries (Efest Purple IMR 18650 35A 2500mAh 3.7v Rechargeable Flat Top) fit very loose even with the plastic OD spacers they provided. The beam is very weak and if you focus it on a wall about 5 feet away, it is more like a line and not oval. I am in contact with Jet Laser and I'll see what they say. Bummer
Yeah, I'm a dumba##, the two flat top batteries were not making contact. Then I saw the two small magnets. Tried them and it worked great. I took out the extender and used two 16340s and that works too.
Really nice laser and very well made. And as Trump would say it is Huuuuge!
And Jet Laser was on top of it, their customer service figured out the problem before I did.
Thanks for the recommendation.
