"Selectech" brand laser. Is it any good?

[Ray1]

I am new to lasers. But I am considering buying a laser made by Selectech. It is 532nm, 200mw, focusable, rechargeable, flashlight size, with safety key for under $100, though this price is a person to person deal, not retail. I cannot seem to find much online concerning this maker, Selectech. I was wondering If this is anything good, or a company I should stay away from. Any and all info will be appreciated. Thanks ahead!

200 watt? :huh:

You mean 200mW? (milliwats)

Is the host like this?

I havent heard of that brand, but I think its one of those cheapy Chineses. (correct me if wrong)

So the laser is most likely underspec..

Have you seen it on? How does the beam/dot look like?

And if you buy it, remember to buy safety goggles too..

if its 200W claimed power it is underspec no doubt

Very simple test for that. Does it immediately start to burn through house walls?:crackup:

Sorry, yes it is 200mw. (I am used to guitar amps)
Yes, the host is very similar to that one, only larger in diameter at one end.
I have not yet seen the beam or dot.

If I do buy it, and the diode ever burns out, what are the chances of finding a replacement diode? Or just a diode that will work.

Green lasers dont use diodes, they use modules that convert ir to green light.
So if it burns out it is very easy to buy a new module and installe it.
Here is a true 200mW module: Green laser module 200mW For custom build or lab
