I was an early backed on Kickstarter, been using the G2 for about 3 months now. I don't really intend to travel with it, but it's small and light enough that you could, definitely lighter than most other fiber lasers in its power range.

The software (GLaser) takes some getting used to, but is very similar to EzCad, so almost any video or tutorial you find on that can translate to this.

Compared to the 2w IR laser I had before, the G2 is so much faster at marking things and can engrave deep when I want to. I've marked a variety of plastics, marked and engraved metals, and engraved slate tile. And after some testing, can even get some colors to anneal on stainless steel.

Support has been responsive, and the community on their Facebook group is helpful as well, with users posting test files, tips & tricks.

Drawbacks? Judged against other 20w fiber lasers the only drawback is lack of LB support, but that is being worked on. Judged against fiber lasers in general, could always have more power or could have a MOPA source (even more/better color annealing), but then it certainly wouldn't be in the price range it's in. Compare against Gweike's G6 series to see how much different that would be.

I'd buy it again

I have had this laser for several month and it is a work horse. It is my most dependable laser i have out of the 20+ lasers in my shop. This one you cants sleep on.

! Perfect for my needs .Very helpful customer service.

After careful consideration and intensive research, I recently opted for the Gweike G2 laser to carry out metal engravings. And I must say, my decision has proven to be extremely satisfactory.

The delivery of the device went smoothly and the device was carefully packaged, which immediately gave me a good feeling. It was surprisingly easy to set up thanks to the well-structured instructions. It didn't take long before I had the appliance ready for use.

However, what impressed me the most was the quality of the laser engravings. The precision and clarity with which the G2 laser works is simply impressive. I saw a video showing the engraving at maximum power and I was mesmerized by how fast and accurate the laser is. In real time, the result is just as impressive as in the video.

Of particular note is the legibility of the QR code I engraved on a piece of metal. Even with the finest details and complex patterns, the clarity is maintained.

Overall, I am extremely satisfied with my purchase of the G2 Laser from Gweike. The quality of the laser engravings, the ease of set-up and the reliable delivery make this device an excellent choice for anyone who wants to do high-precision metal engraving. I can recommend the G2 laser without reservation.
