Not high quality
Our dentist has given us GUM brand denture brushes in the past, but eventually, after a long time, they do wear out.  I bought this brand on Amazon because it cost less.  In this case you do get what you pay for, and that is "NOT MUCH."  The bristles are a bit stiffer than the one on the GUM brand, but the main problem with this brand is that in the holes at the very bottom of each bunch of bristles, it develops that pink "stuff" which is a precursor to black mold.  I tried various ways to get it clean, but even soaking the brush in bleach has no effect.  I will not buy this brand again.
