User friendly, well conceived and made product with good customer service.
As a professional visual artist, I use parts made with my GF in my sculpture. This laser has been critical in enabling me to design and build an whole new body of work as I prepare for a solo museum exhibition. The interface (GFI) has worked perfectly and so far, with the exception of the compact filter, I have had no issues. My interactions with customer service have been very good. I will not post my sculpture here, but here is another project I worked on for a wedding gift.
