I wanted to post a detailed review of this laser, but i messed up and my nice long review was erased from my browser... i will post one later on, but untill then here are some photos and my YouTube videos of this laser

Burning demo: SDLaser 303 200mw green laser - YouTube

Short and pretty useless review: SDLaser 200mw pointer review - YouTube

Nice picture Josh! That looks like a nice little greenie you have there

PS: Post more pics if possible!

Great lillte laser, would like to try some range tests this evening, have a feeling it'll easily make 2.5-3 km! Highly recommended as a first high power laser

If it is actually anywhere near 200mW you'll see a distinct "dot" on low level clouds and a noticeable projection on nearby hills. Be careful where you shine it outside ... While I do sometimes take short vids of me lasing outside (in a DESERTED area) I don't think I'll ever post them as it's ammunition for the "lasers are weapons of mass destruction" crowd.

Hi trencheel!
Yea certainly know about those crowds, have family who aren't happy I have this thing due to their concerns I will use it to cause an Apocalypse :wtf: I would love to try hit a cloud but where I live we Dont get low level cloud cover often... Let it be known that the forst morning or evening we get I will be trying to hit it! Also will never skypoint without flightradar app running (to show where nearby planes are) as local law puts a 10 year jail sentence on anyone who hits a plane with a laser :bowdown:
thanks for your reply

Hello everyone.
Can anyone explain how to disassemble one of those lasers ?
I cannot seem to find a way to properly do it.
Only the battery cap is removable.
I can see the board that has the button contact and arc on it, but that's it. It cannot be spinned so I can't remove it.

Hi overmind.

My switch went dead and just got my replacement unit, couldn't find a way to open it either..

 

[Overmind]

I have the same problem, but it appears to be the contact between the arc and the board rather than the sw/button.

 

[JoshDeet]

Ah I see. Make sure your key switch is making contact and if you Dont mind waiting contact the seller for a replacement unit, here's some pics of my new unit. The removable lens has more patterns but its Identical otherwise

 

[Overmind]

It's long past warranty period.
I'll have to fix it myself.
End key/cap is ok, I tested without it using direct contact.
I managed to get to reposition the arc and seems ok.
I'd still like to know how to open it up tho'.

I have this but mine says laser 303 on it. THe batteries don't last long and its run time is about 1 to 1.5 minutes at a time. It loses power rapidly as it warms up. I think this is more a battery problem more so than a laser one. I will let you know once I get quality batteries and a charger.
