Q: 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

A: Good Review

Q: Good and sturdy. Wish it had one or more small drain holes in it, since it's on the top of a water container. Otherwise it doesn't leak at all like my old filter. Filter is pretty big, probably about 6&#34; tall by 4&#34;wide. Water takes much less time to filter with this filter, compared to using just that plastic bowl. It looks cute though, so I haven't bothered getting another one. I'll get rid of it if we ever have an odor again.

A: Good Review

Q: There are better ways to learn a language than this. This is a bad idea that needs to be addressed and there should be a recall. I'm so disappointed when Amazon doesn't inform customers before selling them.

A:
Bad review
