My daughter LOVES singing and music, so for her 2nd birthday, I bought her this CD player.  At the time,  there were not too many reviews and they were very hit or miss, but really there is not much of market for children's toy radios with microphones so I took a chance and I am glad I did. It's been 6 months now and she really enjoys it.  It has held up well to rough handling by a 2 year old as well as her constantly sticking the microphone in her mouth with the "aaaaaaaaaahhhhh" as another reviewer mentioned.  I haven't bought an AC adapter yet and agree it would be nice, but my daughter likes to move around and dance with it so I'm not sure it would work for her, but truthfully the first set of batteries held up well and I'm now on my second set of batteries after 6 months.  The only things that I think could be improved about this is that: 1) the volume can be a little wonky.  You have to set the volume up very high, like over 20, to really hear it.  The lower volume numbers are ridiculously low.  Also, the microphone seems to have MUCH a louder volume as compared to the music no matter what. 2) The microphone coil is pretty short (which might make sense for safety reasons, but it is not unusual to hear that screeching noise due to microphone interference. Obviously, I would prefer microphone interference to a strangulation hazard, but if they can't make the coil longer, then I think they need to address the microphone interference. 3) while I really like the hold function which prevents the child from constantly rewinding, fast forwarding, stopping, etc. while the music is playing, it has a drawback, which is that the child CAN open the cd player while the hold button is on. So if they are very determined like my daughter, they can succeed in playing with the buttons to make it do something other than play music, such as insert, remove cd player, stick your finger in when cd is spinning. Frankly, I think the open and close feature should be disabled while a cd is playing. Now, these are just helpful suggestions if the maker was interested in improvement, but I am actually really happy all in all with the CD player.  Seems like I got lucky because it's been 6 months and it keeps working. Also, shop around for this, because the prices are highly variable.

UPDATE: This product is still going strong 10 months later.  I would say that the microphone interference can be annoying particularly because you can actually have the microphones turned off and still get a tiny bit of static/interference.  Again, not hugely annoying but still weird. Looking into other CD players with microphone for kids, it seems like this is a problem across the board with some microphones that actually stop working.

The other thing that is great is that my daugther is not yet 3 obviously cannot read yet, but because the CD players had distinctly shaped buttons (some are squares, triangles, octagon/hexagon, circles, etc.) she is able to memorize that the triangle is for playing and the square for stopping, the smaller up and down triangles for volume control, etc. I think this is advantageous for a smaller group of kids than a CD players with all circular button let's say.
