I bought it to my mom and she's been enjoying it. The battery last for couple of weeks, she has a very large area, but only 2 dogs so it's fine
Good Review

Bought from AMAZON for my mother and they work great. They sound clean no noise when playing CD's.
Good Review

These pencils write smoothly, have a nice feel in the hand, and don't bleed through thin paper. I am very disapointed with them, however. When we recieved them (Feb 2013), my son immediately noticed they were "yellow", even though it was stated on box. Even after several sharpening attempts, still no change. After reading reviews online here, apparently these are made of some kind of pigment used to lighten color- seems like an afterthought by Finis.

Bad review
