I did exactly the same Erics Mum and ordered the Supermodel a couple of weeks ago from LD direct. I am wearing it today - it is a lovely colour and this is my first polish by LD. I am quite impressed as it went on really easy - hope it lasts. So now I want to try some more of his colours.
Wish I had waited and then I would have gone for the tsv - I am still thinking about it and then maybe putting the supermodel on ebay as I don't need another bottle of the same colour. And this is a cheap way of trying some other colours.
I have had other LD products - the Crystal files which are fab and buffers etc.
I find it lasts if you add base and a top coat. Got the Nails Inc duo in Boots (thanks to a tip on here) and my supermodel is still looking good. It is a lovely colour. Also like the caramel nails inc which came with Boots pepsi offer looks horrible in the bottle but on the nails it is lovely.
