Top critical review
Does the job!

I can't say I REALLY like this, but it is alright.
Pros: Easy functionality and simple design. I like that it doesn't stick way out (and interfere with things), like the KM18 and KM24, which I have also used (but this has an attendant "con," as you'll see). Once you learn what the buttons and controls do it is easy going. I use this mainly to listen to audio from my phone to my old 2005 Elantra (pre-Bluetooth era -- it doesn't even have a CD player, just cassette player and radio). Built-in mic is adequate during over-the-speaker-Bluetooth calls. I haven't had too much of an issue with people hearing me while driving. This may be more significant and quality indicative because my car isn't exactly "low road noise."
The LED color selection option for the "ring" around it is a nice touch as well.
Cons: It doesn't stick way out there. :) What I mean by this is you pretty much have to feel for the buttons and controls. This was definitely suited more for a specific *orientation* of 12V/cig lighter power socket, namely VERTICAL. Mine sits horizontal and it is at the lower part of my dash, where it meets the shift console. I ALSO use it to charge my phone while driving. Thus, while a cord is plugged into it, the "best" way to orient it within the socket is with most of the buttons on the bottom side, out of sight. The KM18 and KM24 models have a face you can twist and orient toward you, BUT it also potentially impacts the use of adjacent interior parts - you can't exactly make it smaller or shorter. For example, I can't use my pull-out dash cup holders in my 2006 Honda Odyssey while I have the KM18 or 24 in use. They stick out and in the way. Sorry, I know this isn't a review of the 18/24 models, but just trying to indicate a difference between the two designs.
This could be great for you, but you need to consider where your 12V outlet/cigarette lighter is in your vehicle and picture this plugged in and how the buttons on the side would be oriented and seen, if that is important to you. Food for thought: I don't think most pre-Bluetooth era vehicles have vertically oriented cigarette lighters. :) Hope this helps.
