Here are some pics of the one I bought:
Please ignore the shamefully bad application. Nailpolish is one of those things I struggle with because I never have the patience to sit and wait until it dries before doing what I need to do. The colour is called Red Award and it's a really nice deep burgandy colour. I love it! I think it's really pretty and a lot more wearable in a work setting than the bright purples, pinks and oranges I like wearing. The polish applies really smoothly and the bigger brush means that you can pretty much cover your whole nail in one swipe.
You can see how flat and wide the brush is especially in comparison to a standard nail polish brush. The one I used for comparison is from one of my China Glaze bottles. I also have another colour in this 'Professional' range from Rimmel but I haven't really seen any other colours that I want. I really hope that they release more colours in this range because they only have a handful at the moment and they're mainly really safe colour choices. This means there's a few light pinks, golds/bronzes and nude colours. Come on Rimmel, bring on the brights!
All in all this product is still definitely worth a try.
