I used the 45 second top coat as well. It really does dry very quickly, even if I have put a couple of coats of polish on.
I get regular emails from Nails Inc. Koala and it is so tempting to get loads. Many different colours. My hubby just says "and exactly how many do you need, you can't wear them all at once". He is a spoil sport, but I still just do what I want.
