From QVC brands:
I've bought all of the following: Leighton Denny, Nails Inc, OPI, Perfect Formula
I only voted for LD though. First thing I bought was the crystal nail file which I LOVE. I've now started buying stuff at M&S when they have promos on.
I have NI - but don't rate the quality.
I have not bought OPI nail colour - Nail Envy, which I do like using, and Avoplex bought elsewhere which I'm not impressed with.
I have the PF but since using the Shellac, I've not bothered.
In the Other category:
Seche Vite top coat - really is quick drying and very shiny.
L'Occitane Shea cuticle oil tube with built-in brush is a must-have for me.
Away from QVC:
Jessica - which is by far and away my favourite.
Mavala - they do the best ever "greige" shade called ELLE - it's a real chameleon and looks grey, purpley or taupey depending on what you wear.
Orly - lovely colours.
Rimmel 60 Second.
Revlon - the ultimate day-glo coral colour for summer - they've been doing it for decades and it never gets old!
New toy from Boots called a
BRUZZ - it's a British invention as well!
