I have a compass...of course...right leg...It is a bit unconfortable...it really sucks when they hit the same area several times due to layer of colors...I think mine took in the 2-3 hour range...

Choice is yours - just remember it is pretty much permanent...

I always wanted one...never knew what it would be until a few years before I had it done...

Only thing you want to do is make sure that you get a reputable business...and an experienced artist...mine had been doing it for 10 years...
