While I use this product every day, I can honestly say I could live without it. I bought this in Twinkling Gold (the lighter shimmer). While it says on their website: "Twist the handle of this brush and watch a pearlized, slightly reflective powder “magically” come up through the bristles", this isn't exactly the case. Twisting the handle of the brush, hardly does anything. It takes a lot for the powder to actually come up through the brush. If you really want a good amount of shimmer, you'll have to open the back, tap a bunch of powder out, and then dip the brush in it and sweep over your face. If you really want hardly any shimmer, just a dab of it, then you could probably deal with the shimmer hardly coming through the brush, as it will give you a very SLIGHT shimmer. While, when this product does work, it gives a nice glow, I could probably use another product that isn't as defective for the same effect.
