[EX Q]: Great product. Had bought it from PetCo originally, but they no longer carry it. So, I was very thrilled to find it online. It's exactly what we were looking for. A good sturdy tool that our Jack Russell puppy can handle easily.
[EX A]: Good Review

[EX Q]: My mom read this series and we both have enjoyed them. Can't wait for more. Love the characters. Worth reading. Enjoy
[EX A]: Good Review

[EX Q]: This unit failed with only 20 days of use - no way will I be buying from Toshiba again.
