[EX 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
[EX A]: Good Review

[EX Q]: First off, this product came at about 3 weeks after i ordered it. And I'm okay with that,considering how cheap it's priced.
[EX A]: Good Review

[EX Q]: These don't work, they fall off and get lost easily. They are very cute - BUT I regret buying them. A waste of money. Unless you're only using them for one day, don't buy! For regular use, find something better!
[EX A]:
Bad review
