Yet another burning ebay "5mw" laser video

I'm going to try and start a laser channel, and as this is all i can afford right now heres my first:

I do not yet have an lpm, but my guess is around 40-50mw from what i can gather from other videos. Also this is one of 4 that i ordered, 2 of which were burning like so, and 1 of which was super dim even when fully charged. The other started bright and after about a second got dim(dot changed shape too) i know theres a name for that, im still pretty new though. i ended up getting a replacement(which is shown here) and it worked really well! To sum it all up, some work and some dont, make sure your seller will offer a replacement if it breaks.

Are you wearing goggles? You might be getting 40-50mW of 532 but you're getting a hell of a lot of IR also to light matches that fast.
Careful.
dot shape change is called mode hopping. Maybe between tem00 and tem01.
What are the other lasers wavelengths?

Thanks for the warning, i wasnt expecting to even need goggles since it was advertsed at 5mw but they will be arriving soon...

Yeah goggles are a must when you're burning things like matches or anything up close. Did you order the right pair for your lasers? I can give you some links if you need.

yeah since i dont have any rediculously high powered ones yet what would you recommend?

If you are serious about the hobby buy some like this:
Eagle Pair® 190-540nm & 800-2000nm Laser Safety Goggles

If you have any red lasers you'll need a different pair.
