Hello, What is the power of the "Laser Engraver Module Kit 12V 0.5W/4W" available in the Gift Shop? By default, we will have the 0.5W, or the 4W (see the choice on https://store.creality.com/products/laser-engraver-module-kit-12v-0-5w-4w ) Or do we have the choice between the two powers after clicking on "Redeem"? THANKS. [%6839402488] [%2443000667]
