Coco Beau Pro 'The Big, Fat, Firm Foundation Brush'

I bought my Coco Beau Pro 'The Big Fat Firm Foundation Brush' £29.75 after reading some good reviews online.  It's really chunky and the brush part is 3 times the size in depth and 1.5 the width of a regular foundation brush, such as my Mac 190.  The bristles are dense and have a tapered end and the handle is huge, which makes it very easy to hold.

The application of foundation is quick because you are covering much more space, so you can do your whole face in about 20 seconds.  It also doesn't leave any streaks unlike some foundation brushes.

I now always use this brush on myself and for work because it does the job so much better than my other foundation brushes (for the small nooks and crannies of the face I'll use a concealer brush).

This is definitely not for the casual foundation user because of the price but if you are a serious foundation user, want to save time and make application easier, this would be a real bonus to your brush collection.
