Review (2/5): Not as good as Widu was. Needed to replace the brush within a year
I believe Widu became Tek in 2019. My Widu brush lasted 8 years before the latex in the brush head started to collapse and the wooden bristles touched together. The Tek brush started to collapse in the first year (and well past the return date). It was still still useable but in 2 years the bristles are collapsed together and the brush unuseable. That said, when it works, it's comfortable, easy to clean, and I used to love it.
