[Q]: very disappointing product! In less than a year its doesn't work properly! After 40min of use it turns off, no matter if charged or no! Wouldn't buy again
[A]: negative

[Q]: This thing does not tell you which app to download. I turned it on in range of WiFi and it would not connect regardless of which of the 3 apps I used. Thought that buying a cheap product was the way to go... you get what you pay for. In an age of cheap technology, it is astonishing that it comes with so little information. I am a reasonably tech savvy individual, and the fact that I can't figure it out speaks to the low quality of the product. DO NOT BUY!
[A]: negative

[Q]: My cat is a very peculiar girl. She doesn't take well to new things. I thought she might like this heated cat bed, so I bought it for her. Within 20 minutes she was laying and napping HARD in it. She has yet to move out of it. I think she has a new favorite thing. I am so glad I bought this bed.
[A]:
positive
