Anything over 1mw can be dangerous. 405 is deceptively dim and I would hate to point a "1mw" true 50mw 405 in someones eye.
No one should ever discourage safety
So many face palms required
you get what you pay for and all cheap greens are over spec and have lots of IR. Please do some searching it has been covered hundreds of times.
It does not list the part number. So I would doubt it would live long at 300mw I would guess it would be better for about 200mw.
Get a part number from the seller I could be wrong.
The core is a good laser and it is right on spec. It is no to overprices as it uses optical feedback to make sure it is steady power and it is IR filtered.
If you want a true 5mw IR free stable laser the core is a good choice.
You mean the arctic 700mw? I don't think they make any 1W lasers.
No green laser under $1000 is going to make 1W in a handheld version. The rest are a lie about the power.
Ask them what they want to change I am actually curious. Or make them ship the laser first and tell them the changes are on back order until you get some more kilobytes.
I think those are rated at 35mw. But can sometimes be pushed near 50mw. I got 6 and they were very touchy blew a few before I decided to just go normal power at 36mw.
