150 Nova x series vs 150 Premium Optotronic

Until now I bought lasers from Maxon Technogies , Laser Glow , Nova laser ....I was very near to buy from Think Laser and now Optotronic was the last purchase.
So Do Not order ever from maxon technologies also DO NOT order ever from Think laser ....laser Glow is a very good company but they make me a very bad surprise....I asked to do not write the real value on the invoice and they assured me that will not write and very very incredible stupid thing was that they wrote the real value and near it wrote to customs to take care and to not tax me ....very very very incredible stupid guys at Laser Glow ...I payed almost a half from the 700 USD custom taxes like a stupid idiot.
Now I have fear to buy again from Laser Glow....anyhow the Aries laser glow was the best ...was because I broke it and now I purchased RPL 165 mw Opto and is good but I don't understand one thing ....for example if I put one finger on the laser hole of ARIES 150 it burn me in 2 seconds and if I put the finger directly onto the laser hole of RPL 165 mw will burn me in about 10 second.....very interesting is that 165 opto is in fact 186 mw ....

Im not sure, but I think it depends on where your burning you skin. Your skin is more sensitive on the back of your hand, inside of you forearm or biceps as opposed to the grip part of your hand. If you been working outside all summer and have calluses on your hands and fingers this may be why it takes longer, you might just not feel it.

As far as your laser, thats how jack is. Hes great, I love that he tells you what your new toy tested at power wise, but also that they're usually over spec. You purchased a 165, and got a 186. Thats awesome!
