A good deal for who---you, Wallbuys?

Without Laser Power Meter data showing/proving that the item is if fact a 200mw, 532nm is is just another piece of low cost, mass produced, misrepresented garbage that you have never seen and do not know anything about other than what some less than honest supplier who will lie and deceive for money, tells you.

 

[InfinitusEquitas]

I tested one of their "200mW" lasers, to have it be ~40mW with 10mW of IR.

Considering it was only $20 I don't care, but let's not kid ourselves about them being anywhere near 200...

 

[pschlosser]

If that truly were 200mW, then yes, it would be a good deal.

sadry, no.

of course, this is for all members in laserpointerforums

As everyone else has said and InfinitusEquitas has proven, this laser is definitely not 200mW.

I have a red laser in this design, I purchased it for $25 on aliexpress, I dont have a lpm yet, but the best it can do is light black matches, and also the focus of this is by moving the head front and back to focus, and is not very stable, I have to hold it in place for the focus to stay stable. what I liked about the laser though was that the clear part lights up with the laser but it wasnt enough and the dot also appeared to be messed up with small spots on the sides and not a clear focus. Once I check power I will know exactly what it is. However I told this to the seller and he gave me a $10 discount on another red laser, which was $22, so only $12 after discount, and for those prices I think the two lasers are a great deal they have a somewhat visible beam at night. As for this, for $30 you can get a laser that is ~100mW with the sellers posting lpm readings.

this seller has a lot of variety of green lasers and the power is believable, unlike some sellers selling 1000mW green for $30

I'd be interested in some of those if someone other than the seller would post LPM readings.

Thats what I am planning on doing for a few different models, but an issue I have visibly noticed is that the output of the lasers from china is not constant, like same model laser I have 2, if I compare the beam side by side, I can notice one is brighter than the other, both batteries fully charged. I will get exact difference after I get my lpm but thats what I noticed

And sometimes the power is understated .
