I wasn't sure about how I felt in regards to the matte. I tried it with a few colours and it just didn't look right until I did my nails last night with a standard cherry red (Gwen in Ciate ASOS Nail Paints - which is now out of stock sorry!).
This was the matte effect product I purchased from Rimmel and I am pleased with how it holds up - not as good as a glossy topcoat but for the price (£4.50) you can't go wrong. I would definitely add to your collection because sometimes a girl needs a change.
