I've tried all the different brushes and pads but this is by far my favorite. First of all, pumping it up is kind of fun and therapeutic but the foam/consistency it creates is perfection! There's also a cute holder for in the shower and I want to get one of these for all my friends for the holidays!
I found the brush mostly effective to use to get a more thorough cleanse that's not too stripping or aggressive. I like being able to pump it up to my desired hardness. It is a bit tricky to hold the brush without deflating it (you do this by holding down the middle part, whilst you pump by pulling out the handle). It is also a bit too big too really get into the corners around my nose and between my brows. But it's still a lot nicer than anything else I've used, and I love the wall mount it comes with so you can easily air dry it and it won't collect any dust.
The fine bristles work nicely to clean pores but the cushion feature where you have to pump air frequently is frustrating. The directions say to rub the skin for 60 secs, but after rubbing for 15 seconds, the cushion quickly deflates and then you have to pump again. Not worth the effort or price.
