I think everyone feels the problem of dust accumulation on the needle: the decrease in high frequencies, jumps over tracks (which can also lead to scratches).
The brush is very fine, it doesn't create static electricity on the discs, and cleaning is very easy. It's a 'must have'.
I recommend it to all music lovers who listen to music on vinyl. I purchased this product and tried it on SH vinyls from the 60s-70s and I can say that I noticed improvements (don't expect miracles - if the previous owner didn't take care, micro-scratches have occurred - and they can't be repaired). With proper maintenance, you will have perfect listening for many years.
