I bought this product to clean dust from my computer keyboard and Roland TD-27 module. Overall, this brush is very high quality and does its job well.
But this brush came to me in a damaged package and the brush hairs were damaged but not critical for me.
On the base of the brush, I put on an ordinary rubber band from money and specially bought a Thomann Sound Devices MixPre-3 II Bag for this brush - only the brush fit there, not counting the outer pockets.
In general, this is a high-quality brush that can remove dust from any hard-to-reach surfaces, including a computer keyboard, piano keyboard, or electronic drum modules. I even wipe computer mouse pads with it, and everything is fine.
