Hey ive had some 5mw cheap lasers in the past but am now wanting a more powerful laser. I want the beam visible, pop balloons, light matches, and burn black plastic. How powerful should I buy? would 100mw be enough? Ive done a little looking around and found o-like. Are they a good company to buy from? Reliable? Im in the US will that matter? Sorry for all the questions, new to this.
