In the same Walmart reviews, it appears that someone from the Cloudpets team tried to reach out to her so that they could resolve the issue that she was having.

We are so sorry to hear that you had trouble connecting with your husband's phone. We want to work with you to help troubleshoot on how to get this corrected for you. If you will leave your email address we will reach out to you to work on a resolution so you, your child and husband can communicate during his deployment. We thank him for his duty in the US Military! --Your Friends, Cloud Pets
I'm not saying that they'll never get a bad review but they have put together a great Customer Service team to try and help customers get past any issues with their product.
