Lately I know a few people that have been raving about a brand, I may be completely wrong and I will check but possibly could be OPI? I'll find out for you but the reviews have all been brilliant.
Kel - you are absolutely right

OPI... hands down - there is no competition!

My GF has worked as a rep fpr years... lucky me, I have an abundance of colours... everything they make is exceptional quality.

I would still recommend that you use the base & top coats... but I have on occasion forgotten to use the top coat if I'm in a hurry or I've run out... and it still will last you weeks

I have NEVER had to take the polish off because its chipped with OPI - have always had to re paint because my nails have grown and it looks really unattractive

To give you an example - I was painting my toes 4 weeks ago... and 16yr old BIL was mucking around saying he was going to paint his toes bright pink
He was being smart & annoying so I said to him 'come on then, I'l paint them for you'.... he agreed, saying 'Ok, it'll come off in a few days anyway....'

Hhhmmm... I painted them, and its still on there!

He's tried to pick it off, but its not coming.... bwahahahahaaa!!!

I'll have to take it off this weekend when I re-do mine

The polish is fairly pricey (I think compared to other brands... I'm not sure, I can't remember the last time I bought a different brand ) - but it will last you forever.

The quick dry top coat is fantastic - and they have a base coat both for acrylic & for natural nails.

I should get a job doing sales for them after re-reading this post
