Very pleased with the Emblaser 2, no assembly required used straight from the box. The software that comes with it is very easy to use also. It does need to be on a solid work platform as it vibrates quite a bit, something thats easily fixed. The few jobs that I have done to date are far better than my previous cheap chinese diode lasers. Great machine fully recommended don't waste money on the chinese diode lasers you won't regret it. I've now had it 3 weeks, and was an excellent deal. Love the built in safety features, again something not available on low end diode lasers.
