I have been very happy with this brush. The first thing you notice is that it is sturdy and well made. The cap to fill it with detergent seals well, and you can feel when it is fully screwed on. The soap doesn't leak out, even when you store it in various positions (brush up or down, or lying on its side). The "button" to squirt out detergent is well placed, and easy to use. The only (slight) negative is that it takes a bit of getting used to to get the right amount of soap: when it's newly filled with soap, you tend to get too much, and when it's almost out of soup, you tend to get too little, but overall that's a pretty minor thing. I love that it is a brush, rather than a sponge, as sponges harbor bacteria and get stinky quickly, whereas a brush dries out between uses, so I feel like it's cleaner.
