I don't understand why I can't find such important and useful laser tools like these on Amazon or on eBay. Are these still in production? I do not want to get used tools. This is why lathes are so important, you can make these types of tools without relying on the internet.

Here is the video, this laser is really powerful. Playing around with it for the first time, good stuff: One thing I do not like is that it has a circular outer artifact.

Yes, to get a safety hold on it. I hang it on my wall.

You have any recommendations for lens that provides ultra small laser spots? It is 3 element lens right? Laser wavelength will be the sony blu-ray laser diodes at 405nm.

Thanks, yes will do that, you know what kind of wattage tester I can get on a budget?

God I wish there are some mods which has a key to power this thing on. I would never ever leave the batteries inside the laser when not in use... pressing a button is too easy for the curios minds and accidents could happen.

It works :) Aluminum foil did the trick... I'm a bit scared to take off my safety glasses while playing around with this bad boy... I can't see the laser beam, I can only see the laser spot with my OD4+ FreeMascot safety glasses. Any recommendation for a budget friendly laser wattage tester...

Oh god... these stupid batteries I got doesn't work in serial... meaning they are flat top and flushed inwards to the battery, hence not completing the circuit... I guess I'll use some aluminum foil to complete the circuit and return these batteries. I'll get some samsung 30Q batteries. Seller...

What did you do to make the laser turn on? Mine doesn't turn on...

I put two new 18650 batteries and the laser does not turn on when I press the button, no manual came with the laser pointer... I messaged the seller. These are the batteries I bought, I fully charged them took so long...

Well there's always someone with a better opinion. I guess I'll go with IMR.

How long can the battery last from C6 and C8 ? What kind of drivers do they use?

So this bad boy just arrived in the mail, wow that was quick delivery. It came well packaged. I just put the pieces together and seems like a well built laser pointer. I know a battery was not included, anyone have any recommendations what kind of battery I should get? Amazon or eBay links would...

I just got it in the mail. Seems well built and quality laser pointer. All I need now is a battery. Have any recommendations for what kind of battery I should get? Amazon or eBay links would be nice.

Nice website, seems I can sell stuff on Amazon

Well the only thing which worries me is the driver, I haven't seen anyone discussing about it for their 7 watt NUM44 V2 laser build, I just bought the laser from your eBay store just few mins ago... hope I can shoot clouds in the night with a nice laser beam ;). Should of read your comment...

Really interested with your array laser build, im curious how it looks like.

So I am buying a 7 watt NUN44 V2 laser pen from eBay: https://www.ebay.com/itm/324572373013 and it has a PK4 driver: https://www.ebay.com/itm/NEW-20mm-Buck-LED-Laser-Driver-3V-9V-6-Function-200mA-5000mA-NUBM44-/324207130873?_ul=IL Paid a total of: $272.13. Is there any reason I should not...

Hello everyone, So I am trying to build a 7 watt NUB44 V2 laser pen. With my calculation in price, it seems this eBay Ad is selling pretty much the same build cost all ready to be bought and build...

Can a "Super X-Drive 5.5A" driver be used instead? Will it fit inside the SLs S4X host assembly? Also why are you using G8 lens and not G2 lens? DTR's eBay site sells these NUB44 V2 laser units with G2 lens and not G8 lens.
