Because the rotary tattoo machine is quiet,which creates the psychological perception that the tattoo will be less painful. In addition ,they are lighter on the hands. It means less finger and hand cramping, so artists will make fewer mistakes.And this kind of machine was suitable for should be both working which is lining and shading.That's why the rotary machine has chosen by a lot tattoo artist of the world.
In the past few years, tattoo artist who likes the coil machine which is powerful and strong，the coil machine good for the lining,but the sound is louder and heavier than rotary machine.It seems that the electronic device such as the Mobile phone，the different between cell phone and smart phone which is one is able to surfing the Internet, other one has just taking and writing message,it is the similar that between the coil machine and rotary machine that which one can take place market and customer.
In my option, if I was a tattoo artist I will pick the rotary machine，why？Because the rotary machine is light and low sound,and now the rotary machine could be lining.
Other rotary machine which is the rotary pen machine, it looks like a pen that more comfortable and convenience. Some of pen machines without the noise that let tattoo much easier, with powerful motor that should be do lining. I think it depends on person who like coil machine or rotary. I believe that the most supply will make rotary machine，let tattoo artist work better. In general，no matter coil machine or rotary machine and pen machine that is all the good tattoo equipment for tattoo artist，it all be able to make a good work.
