As the leading reviewer of the standard version of this mirror, the company sent me the deluxe version at no cost in exchange for writing a review. In order to avoid being repetitive, I suggest you read my review of the standard version concerning ease of installation and effectiveness of use. Instead I will concentrate on how the deluxe version differs:
1. The surface area is indeed 20% larger. However, I never had any problem seeing my entire face to shave in the standard version. But apparently the company received suggestions from some users to make a mirror with a larger surface area, and this product is it. If you want to upgrade from the standard version, the good news is that you can use your existing wall bracket and do not need to install a new one.
2. The deluxe version has battery operated LED lighting around all four edges. The company has included the necessary three AA batteries, and opening the battery compartment cover to install them is quite simple. No special tools needed, just a coin to turn the compartment from locked position to unlocked.
The LED lighting is conveniently operated by a button on the side, and there are two brightness levels. Push once for the high setting, a second time for the low setting, and a third time to turn the light off.
Although I had no trouble shaving using just the ambient light in the shower from my bathroom lights, the LED lighting is a nice touch, though certainly not essential if you have sufficient ambient lighting in your bathroom shower.
3. Droplets of water will inevitably form on the surface of the mirror, though they will not interfere with your ability to see what you are doing. Nonetheless I like to remove them (as do most users), and the squeegee included with the deluxe version does a better job than the original squeegee. Once again, the original squeegee does work, but the deluxe one works a little better.
Bottom line: This product, like the standard version, will give you a fog free shaving experience if you follow the directions and fill the reservoir with warm water. As I mentioned in my original review, it does not matter if you forget to do this before you start your shower (as I sometimes do). Fill it with warm water at anytime during the shower, and just watch the fog on the mirror disappear (the mirror will of course fog if the reservoir is not filled with warm water).
Whether you buy the standard or deluxe version (which costs an extra twenty dollars) is of course a matter of personal preference since both products work equally effectively. The added "bells and whistles" on the deluxe version are definitely a nice touch. You just have to decide how important they are to you. But whatever version you buy will give you the fog free shaving experience you are looking for.
Update October 26, 2011: After using this for several weeks, I decided that if I were buying something for the first time I would buy the deluxe unit rather than the standard unit, even though the standard unit works just fine.
There are three things that I really like about the deluxe unit : (1) the larger surface area, (2) the way the squeegee works, and (3) maybe it's just practice, but taking this on and off the bracket seems easier than on the standard unit. I still don't use the LED lighting because my shower has plenty of ambient light, but I'm sure other people find that feature useful.
Update May 3, 2012: Still using and enjoying this mirror without any problems. I now tend to empty the water from the mirror a few minutes before my shower ends, because I hate when I forget to do so at the end of a shower, and then have cold water hitting my feet the next time I empty it. The mirror stays fog free even after emptying the water during my shower because the surface doesn't cool off right away.
Update August 6, 2012: The company now has a compact travel mirror (which I have reviewed on Amazon), which you can also use for everyday use if you want a mirror that doesn't require a bracket and glue, but attaches with rubber suction cups (which also lets you move it easily if you want to a different bathroom).
