This is one of the best brushes that I have ever used considering that it also has the steam function and in order to activate it is very simple, I just have to add a bit of water, make sure the better is charged and then just by simply pressing the button, then I have to wait for a couple of seconds and the steam already comes out. I find it to be practical to use because it has a handle which is easy to hold and I didn't even expect this but our cat really enjoys when I clean her fur. It is easy to use and also from what I have noticed the battery holds for quite a long time, cannot exactly how long it takes to fully charge because I just plug it in but I know that it supports fast charging which is great because it saves a lot of time. This is a great brush which is easy to use, it removes the hair properly and our cat loves it,
