I am very pleased with the Pergear LaserStorm L5 pro. The laser is really powerful and I'm able to engrave metal and thick wood which I haven't been able to do with other comparable Laser engravers. The added eye protection built into the laser makes me feel very secure in using this machine. I decided to be extra careful and wear googles but they are optional.
The machine itself was pretty easy to assemble though I wish the images in the manual were a little larger. There are plenty of instructional videos online to assemble it so I was able to get it constructed quickly regardless. Another great thing about this laser engraver is the size and lightweight portability. It weights next to nothing which is awesome if you have multiple workspaces like me.
Overall I really recommend this laser for it's sleek construction, powerful laser for versatile projects, ease of use and safety measures built into it.
