I don't know if it is a lack of communication.... but the price is never the same. I also worry about them using the same files over and over. At times I had forgotten to wash my hands before we got started, but that didn't seem to matter. That bothered me too. The end result always looked nice, but I did get a fungus last year that was hard to get rid of. I just go with natural nails now with silk or fiberglass wraps.
Pros: Results look good
Cons: Worried about sanitation, pricing varies each time
