I've bought quite a few 1mW laser pointers from Ebay, which don't require a license.
Some were dim and only good for dark sites and some were brighter and fine for the backyard - I suspect they were slightly more powerful than advertised, or that there is just variation in the production process. Just keep the receipt to prove you only bought 1mW ones.
They are great for pointing out objects in the sky to newbies, especially if they have binoculars when they can just follow the beam straight to the DSO.
Regards,
Renato
