Work as well as the original version. May be a possible problem with clip at bottom breaking of not careful, but I have never had this happen. The difference that makes this better than the OG is primarily in the brush handle design. Screw mechanism to fill absent on some prior version is great for longevity. The handle is slightly shorter and stubbier, which I personally find better for ergonomics. Seems like will hold up better than version I had where brush head attachment would connect at a point in the handle than was glued together.

Works well, hasn't leaked yet

Like the brush head for certain things - works well and hasn't leaked yet.
