I don't know too much about lasers and how they work all that but my husband does and I wanted to surprise him with a a laser that can burn something at at least 15 to 20 feet away because I've looked online and read lots of reviews and trying to buy one online it's overpriced or they lie and you get ripped off so I thought my best bet to make sure that I'm getting what I'm I'm paying for if I can find someone that can custom building 1 that hopefully don't cost way too much hopefully something under $100 if possible and thank you to anyone that can help me out sorry I didn't know quite what to say hopefully someone can help me
