The Wainlux K10 is a tiny, lightweight 3W laser that I found really convenient for small engraving projects. It did a beautiful job on MDF, wood, and cardstock, and I like that you can use it right out of the box and even run jobs in offline mode with the TF card. Just keep in mind the working area is only 80mm x 80mm, so it’s best for small blanks and craft-style projects.
