I bought this mug/scuttle a little over a year ago, It does exactly what I need it to do! I have not experienced the soap falling into the bottom as another review suggests, and I have found with a bit of practice and a few changes of technique I get frothy yogurt for foam every time. When the shower is hot I fill the bottom and drop in my brush. When I am ready to shave all I have to do is shake out the extra water from my brush and swirl. I have found that it is best to build some froth in the brush and continue the motion on my face ( BTW I use a $9 Omega 10049 Professional Boar Shaving Brush, I strongly recommend it if you want a super solid starter brush ) The best part of this mug/scuttle is if needed I can move completely out of the bathroom ( I live with my GF) and can shave in any mirror. Rinse your razor in the side, keep shaving... Gotta love portability! It also doubles as a brush holder, when I am done, all I do is pour out the water, rinse my brush, and hang it in the open side.
Bottom line is, If you have limited space, and want to keep yer whiskers from being all over the sink, this is the one for you.
