Review: ease of operation - Good unit, it is a nice entry engraver unit. you can do alot of things without getting into a $1000.00 plus machine and if you are not sure if you want to step up to a machine that is going to cost the price of a used car you can upgrade the laser module would recommend air assist and limit switches. the focus adjustment is a little hard to adjust too
Review: Focus, Focus, Focus! - After doing much research I purchased the Longer Ray5 10 watt laser to upgrade from my 5 watt laser. The Longer is a more powerful laser and burns quicker. Once adjusted it burns a fine line and makes beautiful art. The only problem I have with the Longer is the adjusting of the focus. You have to put a block in the back of the module to focus and it has to be sitting perfectly level. If it is not sitting perfect it will print double lines and mess up the whole project! I would like to see them come up with a way to focus where you could see the focus tool. But if you are a beginner or just want a hobby like me the Longer Ray5 10 Watt laser engraver is a good buy for the price.
