Vinylux is made by the people who do shellac polish but with this you don't need a uv lamp or any special equipment. I went for the mini pack with four colours and a top coat which was £20 rather than paying around £16 for one large colour.
With Vinylux you need put the coloured polish on bare nails and then put the top coat on and the whole thing dried in under 9 minutes (which is the best bit in my opinion).
The colour looked good but the polish is quite thin so all ridges showed through so I took it off and smoothed my nails before repainting them.
My opinion on Vinylux....nice colours and it does what it says....lasts UP TO 7 days so technically 2 days is fairplay. I wouldn't buy it again though
