Real Techniques Expert Face Brush - £9.99
In terms of quality you really can notice the difference between the two brushes straight away. The Real Techniques expert face brush is a lot firmer than the ELF option and I feel as if I have a lot more control over how much product I apply. I use this mainly with my Estee Lauder Double Wear foundation and find that it gives really good results; excellent coverage that isn't completely flawless but comes very near to it! Due to the soft fibres my foundation takes a fraction of the time to blend and doesn't leave any of the nasty streaks that I commonly find occur when applying my foundation with a brush. It buffs the product really well into the skin and gives a beautifully even coverage which I'm really happy with!
I'll definitely continue to use this brush and haven't even reached for another one since I bought it. I love it and plan to expand my Real Techniques collection soon!
