Hi,I am an old salon professional and I have turned a leaf to a new market and amazingly enough I found that things have changed. I had my own salon for 26 years and am now back in the open market. I have taken a nail station in a beach community and find that my knowledge is out of date. I need to purchase a new nail drill. The last one I bought was a nail gennie! Boy have things changed. I need some advice about the new drills and recommendations from users. Please help me!
