100mw 520 or 532nm green is perfect for astronomy, just make sure to not point directly at the sky objects. Instead, move the beam around the object.

If there is no aircraft around, it should be safe. Although you should still be careful so you don't distract any drivers, etc. I have to agree with Wikipedia on that one. The dot of the 301 green is really bright but just by staring at it on the wall you're not going to get eye damage...

Hi. I checked on the website that you linked and it just looks like a reseller of cheap Chinese laser pointers. Their so-called Mars is just an ordinary "301" laser. Your can get that laser elsewhere (for example, Aliexpress) for ~10$, and there really is no good reason to pay more than that...

I can't help you with the beam stop, but as for your other question, yes, you can safely look at the beam and even at the dot of a laser that is ~100 mw, unless the dot is really close to you and/or is tightly focused. Just avoid reflective surfaces and do not shine it in the eyes of any living...

1. You will be able to see the beams of both of these lasers, although I doubt that the 488 one will be all that bright. I'm pretty sure that an ordinary 303 green laser would be considerably brighter than that one. 2. Not quite sure what you mean by beam stop. Why not just shine it on the wall...

If you mean 100 mw green, the beam should be visible even in a dimly lit room. In a basement without any light even the cheapest 30-50 mw 532 nm laser will have a really bright beam enough to impress anyone who isn't familiar with lasers. Just look up XM360 on YouTube and check his lasers...

I guess the short answer is yes (30 feet is 9 meters). But what I would also add is that if you use your lasers without glasses a lot, after a while you start to feel quite comfortable with doing so. That is actually not a good thing, because it makes you more likely to pay less attention to...

I'm pretty sure that you can safely use a ~100 mw laser indoor without a pair of glasses as long as you follow two basic rules: 1. No reflective surfaces 2. Make sure that there is a gap of at least a few meters between you and the laser dot. At least that's how I've been doing it for a couple...

They don't nearly drain as quickly as you seem to think, just keep on using it and charge as necessary. Then you will have a better idea of how long the batteries last.

No problem, just keep in mind that on ebay or aliexpress they are not allowed to indicate the real power of their lasers, because in many countries anything above 5mw is illegal. So it can be somewhat difficult to figure out the real power of the lasers there.

Depends on what you mean by scam. Will you receive the product you order from them? Probably. Is it really a 200mw green? Most certainly not. As far as I can see, they are adverting the so-called "laser 303" as 200mw, which is usually around 80 mw (as green), not to mention that it's heavily...

I use one of my lasers to heat up the charcoal for my hookah. It can be pretty annoying to do it with lighter, because that way sparks can hit your hand. But with laser you can do it safely from distance.

While it is true that it is not a good idea to have your batteries shipped together with the laser, I think companies like Sanwu would simply ship them separately, even if you ordered everything together. In any case, it may be worth mentioning that it is perfectly safe to buy a laser with...

Just as a quick note - since Basho's Thor is "brand new", it has to have a glass lens. At least the LPS insist that their Thor lasers come with glass lenses for a couple years now or so...

I remember when I was waiting for my first laser. It was the 304 red from Sanwu. I never received it, because it got withheld by customs. Turns out Sanwu had declared the value in Hong Kong dollars and the customs of my country found it easier to ask me for the purchase documents instead of...

Hello, just a quick comment regarding Laser Pointer Store. They are legit, you most certainly did not get scammed. However, there may be issues in case your laser stops working as their customer support is questionable. Personally, I ordered twice from them. The first time was a year ago, during...

For 1.6w Thor and one other similar laser that I have I use orange glasses from Banggood. They only cost 20 dollars, so that shouldn't hurt your purse too much. Just paste "445nm blue-violet Laer Protective Goggles OD4+ 200-540nm Eye Protection Safety Glasses Orange" on Banggood and they should...

I can relate to your situation, because I also always wanted a laser and only started buying them a year ago. What's interesting is that "Sanwu red" was supposed to be my first laser as well - if you mean the 304 one for 20$, that is. However, that laser never came to me. It got withheld by...

What you just posted looks like Thor H2 Silver version to me. That one, however, takes in 2x 26650 and the green is 1w. Look up Model 890 on Laserpointerstore, I think that's the one you got. If it's 532nm, it's either 50 or 100mw. The 50 one goes for 20$ there, whereas the 100 one is 35$.

Hey all, I have been doing some research on laser companies in EU while purchasing my 1st and 2nd lasers - thought I might share my findings. Why EU? Simply put, for those that want to purchase a laser within the EU without any customs issues, import taxes or other potential troubles that may be...
