I am an owner of a 2.5W Arctic S3... Now what?

I used an online shipping service to purchase a Arctic S3 in the US from the Wicked Lasers website. I got it in the mail yesterday, and to be honest I’m afraid of using it. Before this, the highest powered laser i owner was a 50 mw green laser pointer I got from eBay, so this is definitely an upgrade. I was so excited to recieve it but now that I have it I genuinely don’t know what to do with it. I’m afraid I’ll blind myself if i try to burn things at close distance with it. The only thing I’m comfortable doing with it is shining it in the sky.

As any noobie would, I have a couple questions:

Do I have to wear safety glasses when I point it at the sky? I’m not looking at the “dot” I’m looking at the “line” in the sky?

Can I trust the saftey glasses that came included with it? If not, what is the best eye protection that money can buy?

What extra predautions should I take other than saftey glasses when operating this laser?

I paid a lot of money to smuggle it into the US, but my eyes are priceless. Honestly, I’m a little uncomfortable with such a powerful laser. It is by far the coolest thing I own but it may not be for me. If I happen to want to get rid of it I’m the future, let me know if you’re interested in it.
