Oh boy :eek:... You have to read a bit more about how green DPSS lasers work and how costly it is to build one with this power range.

Then you understood something wrong. All 3 Lasers are DPSS lasers with two cristals stacked together and being pumped by a third cristal that emmits IR light. The first one is focusable too. Both, the first one and the last one do have a wider beam diameter at the output, but that dosn´t mean...

I have to partially disagree. Yes, the internals are the same and the beam diameter is bigger compared to the smaller (<=200mW) lasers, but my deviates less than such a smaller laser unit. I do own a few of the small ones and an overspec 200mw one, but the one from laserer is really a beast...

You can of course try, but like said. Never ship it without tracking. Did you also read this? http://laserpointerforums.com/f41/o-like-i-think-i-got-dud-74943.html#post1083409 If I remember correctly shipping from US to China will be about $35 or a bit more and there is no warranty you will...

Well, i don´t know where you are from, so can´t make a suggestion whom you should ask. But in general it will be less risky to send it to a well known member here with a good reputation than to o-like. O-Like is known to often claim they didn´t recive the item you´ve send, even if you can prove...

Can´t tell how hard it will be, because I´m not familar with this host. Just can tell someone who already disassembled a few hosts, will find out how to disassemble this as well. You of course can try to get a replacement from O-Like, but I guess it will be a nightmare and cost you more than...

If it´s a broken or cold connection it will require to solder it after disassembling the whole laser ( without disassembling the laser unit - I mean the brass module). The grinding noise could be an indication of the spring being twised and making this noise. You can check this by just...

After reading the whole threat I´m quite sure it´s not the tailcap and not the battery but a broken connection or a cold solder between the diode and the driver. (Probably because the driver got twisted to much) So sometimes the battery and the spring is pressing the driver in an angle where...

Would say pretty much the same. Mine is still doing fine while I incrased the output to be 500+ mW and it´s still like new. It can run for a few minutes without getting hot and is still my brightest laser. Even a bit brighter now. So no need to replace it exept there is someone who will offer me...

Well, As I wrote I my review I didn´t measure the divergence of this laser but it´s better than a 200mW laser with a smaller beam diameter. At about 10- 15m distance I´m getting about the same dot size. So compared to the bigger beam diameter at the output this laser deviates much less than one...

It´s not just theoretically possible ;) The above pictures were made while repairing a grenie with a died IR diode. I replaced the diode and realigned the cristals and got 170mW out of it. All you need is a still working IR laserdiode and enough of time to find the sweet spot of your cristal...

Sure you can potmod a greenie as long you keep the current below the max specs for the specific IR pump diode. It´s just almost all new cheap greenies are already running at it´s maximum current and people are killing the pump diodes by potmoding them. That´s why others will warn you not to do...

Not all 18650´s are totally empty at 3.6v or 3.0 V. Some can discharge up to 2.5V but should be charged as soon as possible. For 16340´s it is normal to discharge up to 2.75V. 18650 batteries that are below 3V should be triggle charged at a low current till they reach at least 3V. Or better up...

The first one TJ posted has a much much better host, so if it comes to quality this one is much better than the mini ones. You can make it even waterproof by adding a frontglas into the focus machanism. The secound one TJ posted can be turned into a mini one by unscrewing the middle part of the...

Dude. There is a world beside the Internet. This was shown some years ago on TV so no link aviable. (Maybe there is already a video aviable somwhere on the net, but I don´t remember which channel this was and when this was emitted exactly on TV and am not able to give you a link for everything)...

I think there is no need to argue about black bodies absorbing heat faster and radiating heat faster than other colored bodies, because that´s a sientic proven fact. I also agree with Cyparagon that a paint in general is an isulating layer. But even black paint can improve heat absorbtion and...

Ebay is a totally different story, so don´t compare Ebay rules to international laws. Especially purchasing lasers is always a very risky task and you can´t ask always for a refund for certain reasons. For example you know all the companies lable it as a flashlight that just costs about $20...

It was also not directed to you Infinitus ;) But regarding getting lost there are a lot of national and interantional laws where the risk of getting lost goes over to the customer as soon as the item is being given to the post company that has to ship it to the customer. So the policities of...

What you guys don´t realize is that it´s not the fault of a company if a item gets lost or is taken by the customs. Especially lasers are not allowed in a lot of countries, so if someone orders one, he must be aware of the local laws and the risk it might be taken by the customs. How about if...

Many thanks. I also love the host of my old o-like style 400mW greenie that I got from lazerer. It´s a very solid host too. It has a more simple style but that´s how I like it.
