I have owned another Toilet Tree fog-less shower mirror for about 8 years, its still working great. I like the new one even better. The portrait orientation and smaller bezel make visibility better. And I haven't verified this, but I think the new one holds less water because it seems to fill much faster. However, it still remains fog free for an entire shave in the shower.
Lastly the way the mirror slides onto the mount (piece that sticks to the wall) is a much improved design. The mirror is much easier to get put back on the mount after filling and emptying.
For anyone needing a fog less shower mirror I think this is an excellent option.
My one gripe with the mirror is that it's not made in the USA.
