My name is LZ and I was one of the first to support this product on Kickstarter and very happy I did.
The only issue I have is the open environment of the Emblaser. This is a very big safety concern of mine. Any stray laser light can do major damage to people and pets in the area.
I built a box to house my Emblaser. It was very inexpensive to do. I used foamboard and heavy duty packing tape to make the box with a lid. In the middle of the lid I installed a sheet of Plexiglas 11 7/8 x 11 7/8 that is 455nm safe.
Now when I turn on the laser I am protected from the light and I can still watch what is happening. The included glasses are good but they only protect the person wearing them. I also added a safety switch to the lid. This adds additional protection because as soon as I open the lid the laser turns off.
I got the Plexiglas form http://jtechphotonics.com/?product=445nm-laser-shielding
