I had SNS dip which I have been getting for around 1.5 years. In south east London/Kent it's huge and every nail salon offers it whereas I really had to search for a place near me in SW2 to do this. Overall the experience was pretty good however it's way more expensive than I would pay in Bexley (£15 more) and I feel like as they don't seem to do SNS often they weren't extremely comfortable. They turned out okay but two of my nails have slight smudges, it took longer than it usually does and also some of the activating polishes seemed to be old and drying out. Nevertheless the salon was clean and the staff friendly so I would go back if I couldn't make it out to my usual place as I seriously love SNS with its high shine finish and long lastedness without ruining my nails.
