This is a great sponge brush - for right-handed people! The sponge twists off when you use it in a counter-clockwise direction, as lefties are apt to do, so I really can't use it.The description says that all you have to do to refill it is to twist the sponge. That's true, but to actually get more detergent into the handle, you also have to remove the sponge. So once you twist it, it comes away from the handle. For lefties like me this means a waste of time and detergent as well as a lot of annoyance.I emailed Oxo about this a month or so ago and never even received an acknowledgement. It's not an expensive item, so I'm ok with having spent the money, but I am very disappointed in Oxo's lack of response.So if you're right-handed, go for it. It's a nice kitchen tool. If you're a lefty, keep looking!I emailed Oxo recently and - after a second try - got a response that the item has been retooled. I'll update this review again after I use it.
