Absolutely great advice avoid buying this specific one https://biglasers.com/product/oro-handheld-red-laser-pointer/

If it really has 1W of power which I doubt it, be very careful with it, you have only one pair of eyes. Even scattered laser can be danegrous at this power level

A slongshot is about $20.

Units bruh! That's 1000mW green laser. Green is in the 500nm range
