If anyone is in the market for an item like this, check it out! It actually comes with rechargeable batteries, so you just plug it in at night, and voila... no more dead battery problems. It is totally portable, and if you are having a hard time seeing the screen, you can plug it into your tv or vcr and view it there! It has a built in clock/alarm, and also a headphone jack if you want to use it but not bother others. God... I'm sounding like a total commercial here, so mods, if this is inappropriate, please delete. I just wanted to share this awesome product with others.
