I work for a "fruit company" and do ALOT of presentations. I really like green lasers as they are very bright and distinct. The few green laser products I have tried are a bit clumsy. I purchased the R800 to give it a go and it works great on my Macs. The "start preso" and "black screen" buttons only serve to drop you out of presentation mode in keynote, but everything else works great. The green laser is very bright and the ergonomics are the best I have used. I will be putting it through its paces with 5 major presentations over the next 2 weeks but I have great confidence that this will be my new "go to" device!
